Atlas ETCS enters services in Wuppertal

A new version of Atlas ETCS train control system has entered service on the Wuppertal Suspension Railway, in western Germany, marking the completion of Alstom’s first full train control and signalling contract in Germany.
Following a contract signed with WSW mobil GmbH, Alstom equipped the entire suspended route, including 31 new vehicles and the century-old imperial wagon (Kaiserwagen), with ETCS.
The contract comprises line-side equipment, such as interlocking, radio block centre (RBC) and necessary line elements via train control systems, as well as an interface to the computer-aided operation control system.
The Wuppertal project represents the very first application of ERTMS Level 3 in which track occupancy is solely realised using train localisation performed by the ETCS equipment onboard the train. Alstom replaced the traditional trackside train detection systems such as axle counters with a digital signalling system whereby the ETCS-equipped vehicles communicate their positions directly to the central computer (or RBC) via radio.
“With the successful implementation of this project, Wuppertal is the first city in Germany to use the European train control system in urban transport. ETCS does not only provide for safer and more efficient train operation, but also serves as a basis for many future technologies,” said Jörg Nikutta, Managing Director of Alstom in Germany and Austria.
