Stuart Thomson, CEO and managing director of the Rail Manufacturing Cooperative Research Centre shares how the industry has collaborated on innovation, research, and development across the past six years.
Formed in 2014, the Rail Manufacturing Cooperative Research Centre (CRC) has continued to work closely with the industry to assist the rail sector to adopt future digital technologies and address coming workforce needs.
Stuart Thomson, CEO and managing director of the Rail Manufacturing CRC said engagement from the rail sector, universities, and research institutions has been the key to collaborative research and development. Co- funded by the Commonwealth government, the Rail Manufacturing CRC provides a platform for the rail industry to work together to increase its capacity to innovate.
Thomson said what distinguishes the Rail Manufacturing CRC is its approach to cross- sectoral research. Bringing together the depth of research in universities and the applied knowledge of the rail industry, along with the support of the federal government, the Rail Manufacturing CRC can advance innovation across manufacturing, design and modelling. After six years in operation, the Rail Manufacturing CRC is coming to the end of its tenure on June 30 this year, with the Centre now working to complete its final projects.
“The Rail Manufacturing CRC has worked closely with the rail sector to deliver industry focused projects. During this time of uncertainty due to the COVID-19 pandemic, the team has been working to wrap up projects and manage financial and reporting requirements required before the Centre closes,” Thomson said.
Since 2014, the Rail Manufacturing CRC has been driving the development of products, technologies, and supply chain networks to enhance the competitiveness of Australia’s rail manufacturing industry. Thomson said that despite the closure of the Centre, the CRC has created a culture of innovation that will continue to grow.
“The industry has faced, and will continue to face, infrastructure and innovation challenges in Australia. By developing research projects and teaming up experts to support the industry, we are ensuring innovation meets industry’s needs and requirements to deliver the transformational change required in the rail sector,” Thomson said.
DEVELOPING AUSTRALIAN RAIL MANUFACTURING
Thomson said multinationals have invested in the programs run by the Rail Manufacturing CRC because there is technical expertise based in Australia’s heavy-haul and passenger rail experience that companies know can genuinely assist their businesses. The next challenge for the industry is making sure there’s a pipeline of work to enable investment in capital, research and development, and innovation.
Within the Australian rail sector, a great deal of focus in the last six years has been devoted to the development of condition-based monitoring systems and applications. Thomson said the Rail Manufacturing CRC has worked on a variety of condition-based monitoring projects, including the development of battery control systems that can extend maintenance cycles, the modelling of wheel bearing wear to determine the best maintenance practices, and developing weld modelling software to assist in improving the quality of welding in rail manufacture.
In collaboration with major rail operators, the Rail Manufacturing CRC has initiated projects to develop models to assess predictive maintenance of rail switches for an operator’s network. Predictive monitoring of rail infrastructure has also allowed the Centre to innovate the use of vision systems to identify maintenance needs on overhead wires and associated infrastructure.
The Rail Manufacturing CRC has worked with Downer and the University of Technology Sydney to develop a new technology called Dwell Track. The new innovation utilises 3D infra-red vision to measure passenger congestion on platforms. This information can be used to better understand passenger movement and to assist operators make decisions to limit congestion, alter platform designs, and – in the future – provide real time information to rail staff and passengers. The technology has since been tested in real time at a train station in an Australian capital city.
Thomson said many of the projects at the Rail Manufacturing CRC have a high probability of future commercial success. “We have six technologies that are likely to yield commercial returns in the near future, so that’s quite an achievement,” he said.
Thomson credits the input of the Centre’s PhD scholarship students who have contributed to research projects. Thomson noted they represent the next generation of highly skilled rail employees. “There is a great deal of discussion around future skills gaps and developing the next generation of rail employees. We anticipate that the vast majority of our rail postgraduates, 51 in total, will seek careers in the rail sector, especially if the sector increases local manufacturing post COVID-19.” Thomson said.
CONTINUING INDUSTRY-FOCUSED RESEARCH
Thomson wants Australia to maintain core national manufacturing and capabilities. “Particularly in Victoria there is a lot of movement happening around local manufacturing because there’s a requirement for at least 50 per cent of components in the rolling stock be produced in Victoria,” he said. Thomson believes the industry is working towards a harmonisation of standards and operations. Putting further policies and governance structures to support rail manufacturing in place will allow market growth and further investment in rail.
Further research and development in the rail sector will support the industry in adopting new technologies, building new local industries, and assisting the sector to increase productivity, safety, and sustainability. The Rail Manufacturing CRC expects its programs will benefit ongoing collaboration after the Centre closes its doors.
“A culture of collaboration has evolved over the past six years and will continue to develop. We’ve seen some incredible outcomes and, for example, I think over the next few years there will be a major interest in energy storage for rail,” Thomson said. The Centre has conducted research in energy storage control systems, and also in the battery area looking at lithium technologies for use in trains. Thomson said back-up systems, rolling stock, and below rail condition monitoring are a highly focused research area too.
“The growth the rail industry needs will most likely happen in the next few years,” Thomson said. Improvements in technology and data collection has aided the acceleration of innovation and Thomson believes automation across rail manufacturing and operations will be heightened. “The sector can expect to see increasing automation and the use of artificial intelligence to monitor and control systems and subsystems above and below rail,” he said.
“New skill sets and innovation from the Rail Manufacturing CRC programs has provided a springboard for industry to engage and collaborate,” said Thomson. “I think it’s a very exciting time for the future of Australia’s rail sector. The industry can expect to see advancements in technology that will be highly relevant for major train operations within the country, and will have global reach and applicability.”
Bombardier is helping rail operators achieve zero emissions on unelectrified track with its battery electric units while slashing lifecycle costs.
One of the key benefits of rail travel to the community is its low emissions. Whether powered via overhead lines or an electrified rail, trains offer fast, high volume mobility, and if powered by renewable energy, emissions free. That is, until the wire runs out.
In Australia, nationally there is 36,064 kilometres of track, but only a small portion of that in the major cities has an overhead power supply. In New Zealand, out of the total 4,128 kilometres of track, 589km is electrified. As the non-electrified sections of the network are often outside of major urban centres, getting regional travellers to travel by train presents the issue of running higher emitting vehicles, or undertaking costly electrification works on lines that have fewer services. These factors present an impediment to the zero emissions potential of rail transport, however one that is recently being overcome.
Launched in 2018, the Bombardier TALENT 3 train is a battery-electric multiple unit to fill the gap in-between electrification of entire rail networks and continued reliance on diesel-powered units. The TALENT 3 train can provide an operator with a 30 per cent reduction in the total cost of ownership, when compared to a conventional diesel multiple unit over a 30-year service life. The train is powered by Bombardier MITRAC traction batteries and can run on non-electrified lines for distances of up to 100km. The batteries utilise recent technological innovation in fast charging and high-density lithium ion batteries which can be charged in less than 10 minutes while running on an electrified section of track, or through recuperating otherwise lost energy when the train is braking.
The research and development work that went into the TALENT 3 train was supported by the German federal government, research institutions, and regional German transport operators. Additionally, the technology behind the train was developed by Bombardier in its Mannheim laboratory in Germany. The newly inaugurated €1 million ($1.72m) facility contributed to the battery components for the TALENT 3 train. In Europe, the demand for battery electric units is increasing, as shown in recent orders for trials of the trains in multiple countries.
In Germany, the innovation involved in the development and production of the TALENT 3 train was recognised in late 2018, when Bombardier won the Berlin Brandenburg innovation award. In particular the jury singled out the role that battery electric trains could provide to Germany’s non electrified network. The train could already operate on 30 per cent of the country’s non-electrified lines, and if cost- effective electrification was done at end points, 75 per cent of lines that currently run diesel-powered services could be operated with battery power.
Commenting on the project, Bombardier’s head of sales – Australia and New Zealand, Todd Garvey, highlighted how the train would overcome network limitations.
“It was Bombardier’s goal to develop a quiet and eco-friendly train for passengers, while also offering operators the best alternative to higher emittting diesel trains on both cost and safety aspects.”
In Australia and New Zealand, where there are already proposals for the electrification of sections of regional and intercity track, the Bombardier TALENT 3 train could readily operate on lines such as the Hunter Line, a variety of V/Line services in Victoria, and partially electrified sections of track in New Zealand. However, the flexibility of battery- electric trains enables new connections to be made.
“The BEMU – as we call it – has massive potential in the ANZ market as the cost barriers to deploy widescale electrification are considerable.
“Our BEMU provides operators and governments with a zero-emission alternative to diesel propelled vehicles across their extended networks. Once the electric line runs out, the batteries kick in and the vehicle can continue running as normal for up to 100 kilometres.
“The only additional infrastructure then would be strategically placed charging stations throughout the regional network that the vehicle can plug into, to recharge the battery,” said Garvey.
“This presents big savings and reduces the need for a large-scale civil works program. These battery trains are also quieter, and this is good in greenfield residential areas, for example, where diesel trains might not be the preferred option.”
The key to realising the benefits of battery trains is their flexibility. Not only do they reduce a network’s total emissions but eliminate the immediate impact of emissions caused by the trains themselves. Emissions from diesel powered vehicles can limit their use in inner city areas and confined spaces such as tunnels. In addition, Bombardier’s TALENT 3 can achieve a significant reduction in noise, when compared to conventional DMUs.
Combining the latest in battery technology and a pedigree of innovation, the TALENT 3 provides zero emissions mobility to a much wider audience.
A new report will provide the rail industry with recommendations to ensure that research leads to a thriving technology and innovation culture within the rail industry.
The Australasian Railway Association (ARA) has commissioned L.E.K. Consulting to benchmark the industry’s investment in and use of technology.
The report comes as one of the key sponsors of research in the rail industry closes down, the Rail Manufacturing Cooperative Research Centre (CRC). The ARA highlights that CRCs, including the previous Rail CRC and Rail Innovation CRCs have driven innovation, and without the Rail Manufacturing CRC there will be a “significant void”.
By sponsoring cross-sector research and collaboration between researchers and industry, CRCs have overcome one of the key deficiencies in Australian research and development (R&D), a lack of collaboration between industry and research. This lack was identified as the lowest in the OECD by the federal government’s National Innovation and Science Agenda Report.
Another challenge for innovation and technology adoption in the rail industry is the lack of alignment across the sector. The disparate aims of state and federal governments, purchasers, suppliers, and researchers has created a disconnect between planning, action, support, and adoption, the ARA write in their briefing note.
The ARA highlights that a cohesive business case is needed to support investment in rail technology and innovation.
As part of the research project, the L.E.K. report will benchmark investment, development and adoption of technology, outline the benefits, and challenges for the development and adoption of technology, review and identify solutions and make recommendations.
The potential of coherent investment in rail technology and innovation has the potential to improve productivity in the sector, creating jobs and economic growth. In addition, local investment in R&D can increase local capacity and maintain areas of competitive advantage.
The ARA highlights that the current investment pipeline represents an opportunity for investment in R&D, that can maximise efficiency in the delivery of rail infrastructure.
The report follows increasing calls at a federal level to support local suppliers and producers. Industry Minister Karen Andrews noted that there is the potential to support local supply chains.
“This is about embracing the incredible quality of Australian-made products – products that nations around the world associate with being top-notch.”
Shadow Infrastructure Minister Catherine King said that calls for locally produced goods should extend to infrastructure projects.
“Employing Australian workers and using Australian-made materials on Government-funded infrastructure projects creates more jobs all along the supply chain and ensures that Government investment remains in our community, rather than flowing to overseas companies.
“This should include building trains here and working with the States and Territories to smooth out production, lower costs and build skills and capability.”
Global technology provider Thales has released a new report highlighting the challenges of and solutions to the current coronavirus (COVID-19) crisis in the rail transport sector.
Acknowledging that in many cases transport networks have been on the front line of responding to COVID-19, the report’s authors write that transport operators will need to develop new ways of operating.
“There is no historical precedent for this, no model to work from. The challenge is huge,” the report highlights.
Since the arrival of COVID-19 onto the global stage, a range of challenges have emerged for transport operators. The report categorises these into four sectors: revenue, health, mobility, and climate challenges.
For operators which rely on fare revenue for operations, rapid drops in ridership numbers have had a severe financial impact. In addition, extra cleaning and the introduction of social distancing measures has increased costs, while restrictions on capacity have limited revenue.
Transport has also been identified as an area of concern when it comes to the transmission and spread of COVID-19, placing extra responsibilities on transport operators to ensure the health of their passengers and staff.
Maintaining mobility while staff work from home and cybersecurity threats increase is also a challenge for operators.
Finally, climate challenges have not been altered by COVID-19, and the rail sector continues to play a part in helping communities achieve their emissions goals.
To meet these challenges, Thales has catalogued a range of digital tools which can assist transport operators. These range from using cameras to detect body temperature and compliance with mask wearing, and integrating traffic management systems to reduce crowding by smoothing connections between modes and services, to technologies for remote operations and infrastructure maintenance.
While some of these solutions are in direct response to the COVID-19 crisis, in other cases, the pandemic has served to highlight areas where existing issues need to be overcome. For example, the adoption of flexible train services to adapt to changes in demand and the provision of dynamic passenger information systems.
Amid these uncertainties, Thales highlights that rail operators should start asking more fundamental questions about their services to ensure that once the immediate crisis is over, they continue to provide adaptive and appropriate mobility solutions.
“For now, the priority is restoring services and rebuilding trust,” write the report’s authors. “Looking to the future, the trends point to a need for next-generation transportation systems. Access to secure, diverse and reliable sources of mobility will be vital not only to ensure long-term economic recovery, but also to address wider societal goals.”

The world-first trial of two hydrogen fuel-cell trains in passenger service has been successfully completed.
The two Alstom Coradia iLint trains have passed 530 days and 180,000km of operation for LNVG, the transport operator for the German state of Lower Saxony.
With the trial now completed, 14 Coradia iLint trains will enter service in 2022, replacing the existing diesel multiple units.
Alstom will manufacture the trains and maintain them at its site in Salzgitter. Gases and engineering company Linde will construct and operate a hydrogen filling station near Bremervoerde station.
Jörg Nikutta, managing director for Germany and Austria of Alstom Transport Deutschland said that the new trains are a step forward for emissions-free transport.
“Our two pre-series trains of the Coradia iLint have proven over the past year and a half that fuel cell technology can be used successfully in daily passenger service. This makes us an important driving force on the way to emission-free and sustainable mobility in rail transport,” he said, noting that data from the trial will inform the development of hydrogen propulsion technology.
Lower Saxony’s Minister of Economics and Transport Bernd Althusmann said that the completed trial has a significant beyond transport.
“Alstom has made hydrogen history here. The project is of a great importance to industrial policy that goes far beyond Germany. Here, we are witnessing the first competitive product of hydrogen mobility at industrial level.”
When used, hydrogen produces no emissions, apart from water, and the hydrogen-powered propulsion system also reduces the amount of noise the trains produce. The Coradia iLint has been designed to replace diesel units on non-electrified lines. Enak Ferlemann, parliamentary state secretary at the Federal Ministry of Transport and Digital Infrastructure, said that this was where hydrogen could play a big role.
“Hydrogen is a real low-emission and efficient alternative to diesel. Especially on secondary lines where overhead lines are uneconomical or not yet available, these trains can travel cleanly and in an environmentally friendly way. We would like to see more such applications.”
As one of the leading providers of digital technology in the digital rail sector, Mark Coxon of Alstom explains what changes rail can expect to see in its digital future.
Since the beginning of the modern era, rail has been closely connected to each major industrial innovation. Initially, in the first industrial revolution, the use of steam to textile mills was almost as iconic as the steam-powered train engine, which became the symbol of increased productivity and modernisation during the 19th century.
In the next era, the adoption of hydrocarbons as a source for fuel also enabled the diesel train, able to haul large loads for transcontinental journeys. Simultaneously, widespread electrification and the urbanisation of worldwide populations saw the adoption of electric, underground metro services that have kept crowded cities moving. Now, as the information revolution looks to set to be the next defining wave of innovation, train technology is leading the way in innovation.
Alstom is one of the early adopters of the digital wave in rail, and indeed has become one of the drivers. The significance of this shift is not lost on Mark Coxon, managing director of Alstom Australian and New Zealand.
“Digital Railways doesn’t have quite the romantic ring of the great train services of the past – the Orient Express, the Canadian Pacific or the Trans-Siberian. But digital is the next big wave in the railway sector, and train users can look forward to higher service standards, more timely information and even better ticket pricing,” he said.
The two primary technologies that have come to define digital rail are digital train control and digital signalling. Although there is an array of other technologies, according to Coxon, these tools will have a fundamental impact on the evolution of rail during the current industrial revolution.
“Digital signalling and digital technologies in general will have a huge influence on the evolution of rail services. They are just the latest developments in an industry that has a great track record (pun intended) of technological innovation. From steam to diesel to electric power, the railroad’s evolving technologies have unleashed economic potential and social mobility wherever the rails were laid.”
Indeed, the new technologies exist in order to improve the usefulness of rail networks, rather than being a cosmetic add on.
“Today we are entering an age where digitalisation allows operators to have real- time information on train movements and analyse overall performance – ultimately reducing costs by streamlining processes and improving efficiency and reliability,” Coxon said.
UNLOCKING THE URBAN
For many cities, including Australia’s urban centres, the efficiencies promised by digital rail could not come soon enough. Traditional signalling systems have reached the end of their useful life, while patronage continues to increase. Additionally, building new rail lines through cities is often not an option, and tunnelling underneath poses significant cost challenges. This has put pressure on existing technology, said Coxon.
“Railways have been part of the urban landscape for so long that networks in many countries have become extremely dense, especially on commuter lines in major cities, making it difficult and costly to implement major upgrading projects. Instead, the kind of improvements in efficiency that digital technology excels at can have massive operational impacts.”
Digital rail can also extend to find connections with other forms of transport, across heavy rail, metro, light rail and also bus and micro-mobility networks. Finding these efficiencies in the digital ecosystem can deliver major benefits to transport and city planners.
“Digital technologies hold out the promise of true transport integration, linking main-line rail services with other urban transportation modes, enhancing efficiency and passenger convenience,” said Coxon. “The introduction of Information and Communications Technologies (ICT), Intelligent Transport Systems and open- data/open-source transport applications are transforming urban transportation, optimising the efficiency of existing and new urban transport systems, at a cost much lower than building new infrastructure from the ground up.”
Within the railways themselves, the enhanced data and feedback gathered by digital sensors form a connected railway that can reduce costs and improve service delivery.
“New transport data collection technologies are also being deployed to provide information about delays, downtime, and predictive maintenance which could lead to huge improvements in service standards, safety, and unlocking the potential of railways. Passengers will also be able to make real-time decisions about their journeys based on the features that matter most to them such as reliability, safety, travel time, and cost,” said Coxon.
In addition, as governments and individuals increasingly identify a project’s sustainability as a key factor, adopting the digitalisation
of railways can enable railway operators to reduce energy usage, improving air quality, while also delivering a seamless experience for the commuter.
“Enhanced safety, predictive maintenance, and automated driverless operation are all part of rail’s future,” said Coxon.
PUTTING THE PASSENGER FIRST
Perhaps an even more fundamental shift will be occurring in the way that passengers interact with transport. Currently divided into discrete journeys often limited by transport mode, a connected digital railway can enable the rise of Mobility as a Service (MaaS). Via data-enabled apps, commuters can move through transit modes made as one seamless trip, with real- time information to smoothen the transition.
“From the passenger’s perspective, access through online apps to real-time information on travel times, potential service interruptions, ticket prices, seating arrangements and even on the least crowded places to wait on a station platform, will enhance convenience and reduce the stress of travel,” said Coxon.
Reducing disruptions also enables transit time to fit into the other rhythms of daily life, with enhanced services available onboard.
“Railways today offer a connected service all along the passenger journey with on-board Wi-Fi for internet and entertainment options. Passengers are able to experience these services using their own mobile devices –laptops, tablets and smartphones,” said Coxon. “This approach to train connectivity can unquestionably deliver a significantly improved passenger experience.”
These developments occur as part of a strategy of putting the individual first, rather than forcing the individual to comply with the requirements of the service.
SEIZING THE DIGITAL FUTURE
However, just as digital rail offers solutions, there are challenges too, as Coxon acknowledges.
“The path to digitalisation will not, of course, be entirely smooth.”
The benefits of digital rail require collaboration and coordination between companies, agencies, and organisations that have up until now existed in their own silos, with limited interaction. In addition, the skills and knowledge that is required to build and run a digital rail system is quite different to those needed in an analogue rail environment, although Coxon notes that these changes could have their own benefits.
“Despite the challenges, the railway sector’s move to digitalisation is clearly unstoppable. Digital technology in the railway sector will see a shift from the traditional emphasis on heavy engineering, to software and data handling skills. In the future, once the hardware is installed, upgrading a signalling system will no longer require hundreds of workers out on the tracks; it might be more like upgrading the software on your phone.”
Getting to this digitally enabled future may require some difficult transitioning, however through collaborating across industry lines, returns can be found.
“Rail operators should take this digitalisation opportunity to integrate different mobility options into their existing offering and consequently focus on value creation through innovation,” said Coxon.
“Without a doubt, it is the quiet efficiency of digital technology that will take rail systems and their passengers into a new age of rail travel that is safer, more convenient and comfortable, more economical, and more climate-friendly.”
Melbourne’s iconic tram network operates across 250km of double track. Xavier Leal from Keolis Downer shares Yarra Trams’ latest innovation strategy that is digitising the network’s 5,000 daily services.
The world’s largest operational tram network has been transporting passengers in Melbourne for over one hundred years. Xavier Leal, manager of innovation and knowledge at Keolis Downer, acknowledges that operations throughout the urban tram network have considerably advanced since the first tram line was pulled by horses in 1884. As the operator of Yarra Trams, Keolis Downer has been investing in its digital strategy to prioritise data collection and improve passenger experience.
Leal has almost fifteen years of experience in strategy and innovation management. Since he joined Yarra Trams in two years ago, he has been driving forward innovations in the business that support enhanced passenger experience, operational effectiveness, and safety in the network.
Before his current role at Keolis Downer, Leal worked in the mobility and transport sectors in Europe. He has led a wide range of international projects that explored digital innovations and defining technology diffusion processes. His previous projects include developing innovative information and technology services, including T-TRANS and Collective Intelligence for Public Transport in European Cities (CIPTEC). Leal said Keolis Downer leverages its worldwide operational experience to explore innovations in smart cities through a digital mobility observatory.
Leal highlighted that it is important to note the difference between tram networks in Europe and Melbourne to understand how investment in processes will allow Melbourne to set an international benchmark for light rail infrastructure.
“Melbourne has a unique tram network. Trams elsewhere don’t have the same challenges that we have here. Not only is it the world’s largest operational tram network with over 250km of track and more than 1,700 stops across the city, but 75 per cent of the network is shared with road vehicles,” Leal said.
This means trams do not have separated corridors on Melbourne roads and operate amid buses, cars, cyclists, and pedestrians. This brings particular challenges with safety and operational performance, particularly travel times. Melbourne’s tram network could run more efficiently. To enhance network capability, Yarra Trams have used technology to enable faster services.
However, due to the nature of having assets distributed widely across the network, including the vehicles themselves, stations, and other monitoring points, there is the potential for the accumulation of digital data to support the more efficient operation of the network. Yarra Trams has recognised this, and is looking to digital innovation, with a number of projects deployed to target priorities including faster travel times, reduced disruptions, and customer safety. These initiatives include digitising asset management through real time-based platforms, to exploring crowdsourcing of data for safety and unplanned disruption management.
One project that Yarra Trams has trialled is the on-board collection of image-based data on traffic. In developing the technology, Yarra Trams took a consultative and collaborative approach by incorporating feedback from multiple stakeholders which come into contact with the relatively open network.
The development team looked to how they could incorporate real time data on traffic volumes to maximise operational efficiency and passenger experience. However, solutions were not always going to come from within the organisation, and Yarra Trams looked for partners who could enable this digital data project.
“Effectively engaging with the innovation ecosystem is another critical success factor to maximise digital technologies,” Leal said.
Keolis Downer collaborated with the Australian Integrated Multimodal Ecosystem (AIMES) to procure Toshiba’s traffic sensing technology. Leal said the data collection and analysis system was based on image processing and deep learning technology in a smart transport cloud system. A trial of traffic sensing by on-board unit (OBU) based image processing technology took place in March 2019 with two C2 trams travelling on route 96 from Brunswick East to St Kilda Beach.
Leal said the trial tested the capability of the technology to detect various states of traffic by deploying image processing techniques and transmitting the results to a cloud system. The OBU could detect traffic in terms of volume, vehicle queues, vulnerable road users, pedestrians and obstacles.
HD cameras captured real time traffic and processed and measured the information as it happened. The information collected from vehicle queue lengths waiting at red signal and pedestrian flow assessed traffic conditions to
a degree, while also detecting obstacles and service adjustment.
The OBU system consists of three units, a stereo camera, image processing hardware, and a signal divider. The OBU system sends detection results back to a central server. These results include images that have been tagged with GPS data. The trail enabled Yarra Trams to obtain geographically precise data to illustrate issues in the network in real time, enabling faster responses and comparisons with historical data.
The digital data collected throughout this trial may allow traffic management and operation control staff to instantly evaluate risks as well as predict needed safety measures.
“It was a successful project,” said Leal. “We assessed the system capabilities
to detect traffic volumes, vehicle queue lengths at intersections, pedestrian crowd volume detection and estimation around tram infrastructure. Now we are discussing with Toshiba, government stakeholders, and Melbourne University researchers the next steps to further evolve the system,” Leal said. Leal is proud to pioneer the use of digital data to evaluate complex transport networks. He said it’s not uncommon for large networks such as the Melbourne tram network to experience unplanned disruptions, so managing data from Yarra Tram allows a clearer understanding of behaviour of motorists, pedestrians, and other vehicles which the network comes into contact with.
Leal said trams and light rail services are the lifeblood of Melbourne, as they are the primary mode of public transport for inner suburban residents. Globally, more than 200 cities are now recreating, building, or planning tram networks. If the Melbourne network were to be rebuilt today, it would cost more than $20 billion and take several decades to complete.
“It’s important to us to have a holistic approach to our digital strategy, that leverages Keolis’s expertise in mobility and digital technology with a robust data management platform that aligns with the Department of Transport’s systems and tools,” Leal said.
“We are increasingly gaining more data flowing from digital channels. From a passenger experience perspective, it is important for us to integrate reporting capabilities with analysis of inputs coming from diverse channels,” Lead said. He said the company expects these channels to grow and further diversify as new streams of data and incorporated into the network.
“We are committed to keep pushing for further integration of information and data to ensure the right actions are taken to enhance Melbourne’s dynamic network,” he said.
While digital engineering has long been touted as the next technology that can create, manage, and utilise data for infrastructure development, the coronavirus (COVID-19) pandemic has brought it even more into focus.
With workforces forcibly distributed as remote working directives took effect, the value of having a rich virtual building information model (BIM) to enable seamless collaboration across physically distanced workforces has never been clearer.
Consulting company GHD has already exploited the value of digital ways of working in many projects, and recently in its work on the Forrestfield-Airport Link project – part of the Metronet project in Perth – within the Salini Impregilo and NRW Joint Venture.
According to GHD’s Rail Design Lead on the project, Martin Harle, using digital tools such as BIM, geographic information systems (GIS), analytics, coding, and automation, the team was able to eliminate clashes between different models by coordinating design through one model.
“Using this technology we are able to automate clash checks across multiple complex disciplines, highlighting design coordination issues in real time,” he said. “It helps to pre-empt and resolve potential construction problems during the design process, rather than dealing with unexpected issues as they occur on site.”
Avoiding duplication and replication, the BIM system enables costs to be reduced at the design phase. This not only improves processes at the construction site, but also enables suppliers to have a clearer idea of the concepts their assets will be working in.
“So far, on the Forrestfield-Airport Link, rail track and overhead line equipment has been designed and modelled 8.5 times faster and 1152 hours have been saved in automating 180 Navisworks exports,” said Martin.
Incorporating digital tools early on in the construction of a project can also lead to efficiencies once the project is operational. At the end of the design and construct phase, asset information can be handed over to the operator to promote ongoing efficiency.
The insights that GHD has gathered from this project have been used to advantage on other projects, including the Sydney Metro. And the lessons have wider implications through the Digital Engineering Code of Practice which will be applied nationally through the Rail Industry Safety and Standards Board (RISSB), which GHD helped design. GHD BIM lead – Western Australia and co-author of the code Belinda Thompson, said the benefits of the code are broad.
“By adopting Digital Engineering processes, increasing the accuracy of information and automating the data exchange processes, we can improve safety, reduce risk, achieve greater cost certainty and improved sustainability.”

In her column, CEO of the Australasian Railway Association Caroline Wilkie highlights that Australia’s rail freight network is facing challenges during the COVID-19 pandemic but its importance now is greater than ever.
Australia’s population is forecast to double by 2070, reaching almost 45 million people. This growing population requires an increased allocation of goods, adding pressure on our existing freight networks to deliver. According to the National Freight and Supply Chain Strategy, Australia’s freight task is expected to grow by over 35 per cent between 2018 and 2040, an increase of 270 billion tonnes, bringing the total volume moved to just over 1,000 billion tonne-kilometres.
The role of rail freight is critical in meeting this future demand and maintaining our international competitiveness. The Value of Rail study commissioned by ARA in 2017 highlights that a one per cent improvement in freight productivity could generate $8-20 billion in savings to the national economy over 20 years. Rail freight provides a cost-effective, safe and environmentally sound solution for reducing congestion from heavy vehicles on urban, regional, and interstate roads. Just one freight train alone can take 110 trucks off our already congested roads and rail is up to nine times safer than road freight. In light of these significant benefits, the ARA is working with governments and industry on behalf of our members to get more freight on to rail, and to improve the efficiency and productivity of Australia’s rail freight supply chains. Achieving modal shift to rail is critical to increasing economic growth, improving the liveability of our cities and supporting regional communities.
Delivery of the Inland Rail project is an important step in achieving this. This nation building project will see a 1,700km freight rail line directly connecting Melbourne and Brisbane, via Toowoomba, Parkes, and Albury. The route will utilise approximately 1,100 km of upgraded existing track and 600 km of new track in Queensland, New South Wales, and Victoria. Most importantly though, it will bypass the heavily congested Sydney network and bring rail freight travel times between Melbourne and Brisbane down from 33 hours to less than 24 hours. This is a game changer and will make rail freight much more competitive over long haulage routes.
In a period of economic uncertainty, the Inland Rail project is bringing a much needed boost to the economy. Construction is already underway on the Parkes to Narromine project and planning is well advanced on a number of other sections. Approximately $747m has already been spent, with much of this spend being injected into rural communities.
Inland Rail has been in the public domain for over fifteen years. It is also one of the most heavily studied projects in recent Australian history, having been through an extensive consultation, planning, route analysis, engineering and costing process.
We are aware of issues that have been raised in relation to flooding of the Condamine crossing in Queensland.
Without a doubt, the project is receiving the best possible expert advice and can manage these issues using tested and proven mitigation measures. These issues need to be worked through carefully and collaboratively, but they should not delay the delivery of the project.
The delivery of Inland Rail is a start, but more must be done. Investment in rail freight delivers enormous benefits in the long term. Improved supply chain connectivity and productivity benefits the economy and the environment and helps provide resilience in the face of emergencies like to COVID-19 pandemic.
The current crisis has just reinforced the importance of a highly productive and efficient supply chain. This unprecedented event has challenged our supply chain like never before, but our rail freight members continue to ensure that essential goods such as canned food, toilet paper, and cleaning products are moving across the country and to customers.
When state border crossing restrictions came into force in later March, the ARA wrote to state and the Commonwealth transport minsters to ensure rail freight was considered an essential service and exempt from border restrictions.
However, the stark difference between road and rail freight regulation is never more apparent than it is during times like these. Regulation by the National Heavy Vehicle Regulator (NHVR) has a focus on both safety and productivity, whereas the Office of the National Rail Safety Regulator (ONRSR’s) remit is purely safety-related.
The ARA have long held the view that we must take a national approach with all modes working together to deliver an integrated freight market. However, this approach can only work if all modes operate from a level playing field with equal treatment in terms of access pricing, government policies, and the role of productivity in regulation.
At the beginning of the COVID-19 pandemic, trucks were able to have curfews lifted to extend delivery windows in NSW and Queensland. However, due to the nature of our infrastructure and the shared tracks of passenger and rail networks, our industry does not have the same flexibility. As a result, we must look for other solutions to improve the productivity of rail freight.
Rail freight operators are committed to the highest levels of safety compliance but are routinely challenged by Rail Safety National Law (RSNL) derogations that exist, most notably the differing fatigue management requirements in NSW and Queensland, and the different drug and alcohol management requirements in NSW.
As I outlined in my March 2020 article, these inconsistent, state-based regulatory requirements go against the objective of national regulation and add costs to rail freight without any proven safety benefit. The ARA believes that multiple layers of often conflicting regulation impacts rail freight productivity.
A modern, risk-based approach to rail safety that focuses on productivity will improve our supply chain resilience and unlock significant economic and environmental benefits for the whole country.
