Alstom first to achieve certification for latest ETCS standards

Alstom results

Alstom is now the first company to be fully certified to the latest onboard and trackside European Train Control System (ETCS) standards.

Issued by independent railway certification and testing organisation Belgorail, the new certification allows for Alstom’s technology to be interoperable with Baseline 3 Maintenance Release 2 for the complete railway system.

“We are proud to have yet again set a new standard in rail. We are on track to gradually replacing all the existing incompatible systems throughout Europe and to optimising and boosting the international freight and passenger transport,” said Jean Francois-Beaudoin, SVP Alstom Digital Mobility.

ETCS is widely used throughout Europe for mainline and high-speed systems. In addition, the technology has been adopted internationally, with ETCS being implemented on Brisbane’s Cross River Rail project and on the Sydney Trains network. Other countries such as India, Taiwan, South Korea, and Saudi Arabia have also adopted the European standard.

ETCS uses a digital radio-based system of train control, removing the need for trackside signalling equipment. Movement authority is transmitted to the cab of the train via GSM-R or GPRS mobile data technology. Train location is determined by balises and sensors and the onboard computer determines the maximum possible speed based on train location and track data.

The deployment of ETCS is marked by sequential baselines, of which Baseline 3 is the latest. The baselines set standards for the interoperability of physical in-cab and trackside equipment and software. The latest standards incorporate specifications for the use of more advanced radio technology such as GPRS, with GSM-R technology to be phased out in the 2030s.

Alstom supplies ETCS equipment via its Atlas solution, which represents 70 per cent of the world’s onboard rail systems in service and 18,000km of tracks wordwide.

9,000 trains globally have been equipped with the Atlas onboard solution, and 1,100 vehicles will be equipped with the Baseline 3 Release 2 solution.

Alstom is the first manufacturer to apply ETCS Level 3 in Germany, which involves a higher level of communication integrity to move to ‘moving block’ spacing.
