The SD-100 and SD-160 are light-rail vehicles manufactured by Siemens. The SD-100 uses motors that run on direct-current electricity (DC motors), while the SD-160 model features newer motors that run using alternating current (AC motors). 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), Calgary (SD-160) and Edmonton (SD-160).

Technical details[edit]

The SD-160's dimensions are 24.802 metres (81.37 ft) by 2.654 metres (8.71 ft) by 3.811 metres (12.50 ft) 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 80 kilometres per hour (50 mph). It accelerates at 1.07 m/s² and decelerates at 1.31 m/s², with emergency braking deceleration of 2.63 m/s².[1] The brakes also serve as a generator, passively regenerating power back in the city's electrical lines.[2] 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 total length is still less than 25 metres (82 ft), allowing three vehicles to be combined and still be under the 75-metre (246 ft) maximum length of a German streetcar consist. Each vehicle also features an onboard closed-circuit TV security camera system for increased passenger safety.[2] Unlike the Siemens SD-100, the Siemens SD-160 doesn't uses the Bi-Folded Doors, it now uses the Sliding Door similar to door feature on the Siemens S70. In addition, both can be used together in trains consisting of SD-100s and SD-160s.
