Stadler Regio-Shuttle RS1

The Regio-Shuttle RS1 is a diesel railcar widely used for local rail services in Germany and the Czech Republic, and its most distinctive feature is its trapezoidal window frames. Around 500 units were built between 1996 and 2013. It began as a product of ADtranz and was later manufactured and marketed by Stadler after Bombardier had to sell the Berlin-Wilhelmsruh production site in 2001 for antitrust reasons following its acquisition of ADtranz. Deutsche Bahn classes it as Class 650 and Czech Railways as Class 840 or 841, and many private railways also run it. It is a standard gauge railcar built to UIC standards, with 65 percent of the floor at low level and two independent diesel-mechanical drive units, for example from MAN, that burn diesel or rapeseed biodiesel. The angled pillars visible at the windows, which resemble a timber bridge truss, were proposed to ABB, later ADtranz, to save weight, and up to seven units can run together under one driver.
