Atlas ERTMS Level 2 begins Spanish high-speed commercial service

Posted: 16 July 2019 | | No comments yet

The digital signalling solution allows the Valladolid-León line trains to run at increased speeds of 300km/h without the need for physical lineside signals.


Alstom’s Atlas ERTMS1 Level 2 train control system has entered commercial service on the Valladolid-León high-speed line in the north of Spain.

This has come following extensive testing of reliability by ADIF and approval by the Spanish Railway Safety Agency (AESF).

This entry into service follows the 2014 contract from Adif, awarded to an Alstom-led consortium2, to upgrade the Valladolid-León section with ERTMS Level 2 technology, including maintenance for a period of 20 years.

Alstom’s Atlas ERTMS Level 2 is a digital signalling solution that allows trains to run at higher speeds without physical lineside signals. The solution will see the Valladolid-León line running with increased safety and availability, as well as train speed, with maximum speeds increasing from 200 to 300km/h. The resulting updated timetable will allow passengers to benefit from shorter journey times.

The contract includes the design, procurement, installation, commissioning and 20 years of maintenance of the signalling, fixed telecommunication and Automatic Train Protection systems, the centralised traffic control (CTC), security equipment, the mobile GSM-R communications equipment and infrastructure for trains and mobile phone operators.

 “We are immensely proud of this entry into service. This is the second ERTMS Level 2 signalling system commissioned in Spain, after the one also installed by Alstom on the new Albacete-Alicante high-speed line, where Alstom was also the consortium leader. This demonstrates Alstom’s technical expertise and leadership in the field,” said Antonio Moreno, Managing Director of Alstom in Spain.

With projects in 30 countries, Alstom has installed nearly 40% of the trackside ERTMS Level 2 equipment in service in Europe and equipped over 8,000 trains of 200 different types with its Atlas ERTMS solution. Atlas is a scalable solution that can be adapted to all types of traffic and operational needs: passengers and freight, high-speed or suburban.
