CAF presented a first implementation of the Virtual Coupling mechanism using two fully operational rail tramways at InnoTrans international exhibition, which was held last September in Berlin.
Under the name “Connected Trams” this world premiere showcase involves the first deployment of the new TCMS wireless train backbone to control functions like propulsion, braking, doors, lights or passenger information. The control of distance between vehicles is achieved through sensor data fusion and transmitted information between both trams, together with the use of tram dynamic models.
This development lays under the Shift2Rail initiative and will serve as foundation for the incremental design and implementation of whole system-wide Virtual Coupling based operation. Virtual Coupling of trains will revolutionize in the next years railway operations by increasing capacity and flexibility dramatically”
