Alstom has secured a €17m signalling contract with Wuppertal’s transport agency WSW mobil for the supply of the Atlas 400 Level 2+ European rail traffic management system (ERTMS) control and command system for the Schwebebahn suspension monorail in Germany.

Under the deal, Alstom will deploy the trackside and onboard equipment on the 13.3km line, which includes 20 stations, two depots, 31 new articulated trains, which will become operational in 2015, and the century-old Kaiserwagen rail vehicle.

The new signalling system is based on ETCS Level 2 technology, made up of trackside and trainborne sub-systems and, according to Alstom, this is its first German order to cover all aspects of signalling, from route setting and interlocking to train protection and control.

Upon the end of the project, the Wuppertal transport agency will operate its vehicles under ETCS Level 2+ supervision, without lineside signals.

Alstom said that the ETCS Level 2 will be similar to Level 3, with the train reporting back its location rather than using track circuits or axle counters detectors. The new system will allow the trains to communicate their positions to the central computer (RBC), replacing the information of the track occupancy usually delivered by the axle counters or by track circuits.

Compared to the ordinary standard ETCS Level 2 implementation for railways, the communication between RBC and the computer on-board European vital computer (EVC) will be based on Tetra radio instead of GSM-R, the company said.

Alstom’s ETCS centre in Charleroi, Belgium, will develop the system, while the components will be built at the company’s sites in Villeurbanne, France and Bologna, Italy.

The systems will be integrated and commissioned by Alstom’s engineers from Charleroi, Salzgitter and Berlin in Wuppertal, Germany.
