The SD-100 and SD-160 are light-rail vehicles manufactured by Siemens. The SD-100 uses motors that run on direct-current electricity while the SD-160 model features newer motors that run using alternating current. Both models are suited for loading at street level and high-platform level. The two models of car are in use in San Diego (SD-100), Salt Lake City (both models), Denver (both models) and Calgary (SD-160); Edmonton has also recently placed an order for SD-160s

Technical details

The SD-160's dimensions are 24.802 m by 2.654 m by 3.811 m and can be used in trains of up to six cars. It is powered by four AC motors which provide a maximum of 580 kW and a maximum speed of 105 km/h. It accelerates at 1.25 m/s² and decelerates at 1.34 m/s² with faster emergency braking. It has a passenger capacity of 236 passengers (standing) with 64 seats.

Regarding its predecessor, the Siemens-Duewag U2, its driver's cabin is significantly larger, but the length in total is still slightly below those "magic" 25 metres, which times three equal the maximum length of a German streetcar consist.
