Siemens developed four-car electric multiple units known as Class 350 on the Desiro platform. The vehicles, which were purchased from 2004 onwards, have an output of 1500 kW and can be powered either by the direct current rail next to the track or by the 25 kV overhead line. The top speed of the first two series is 180 km/h, while series 3 and 4 are approved for 160 km/h.
