Stadler Regio-Shuttle RS1

The Regio-Shuttle RS1 is a diesel railcar widely used for local rail services in Germany and the Czech Republic. Its most distinctive feature is its trapezoidal-shaped window frames. Around 500 units were built between 1996 and 2013. Originally a product of ADtranz, the RS1 was subsequently manufactured and marketed by Stadler after Bombardier was required to sell the Berlin-Wilhelmsruh production site in 2001 for antitrust reasons following its acquisition of ADtranz. The Regio-Shuttle is classified by the Deutsche Bahn as Class 650, by the České Dráhy as Class 840 or Class 841. Numerous private railways also operate Regio-Shuttle cars.
