The Siemens SD-400 and SD-460 are electric light rail vehicles (LRV) built by Siemens Mobility, a division of Siemens AG. Both models have a common design, with frames built upon a B-B-B truck configuration mounted underneath a double-ended articulated body, which has a seating capacity for 72 people and room for an additional 106 standing passengers. There are four high-level, inward-opening "blinker" doors on each side of the vehicle for level boarding, along with an additional low-level, right-hand side doorway and steps at each end of the vehicle for low-level boarding.

Both the SD-400 and SD-460 are powered by four individual Siemens IGBT electric traction motors with each one developing 200 horsepower (149 kW) and creating a combined total power output of 800 horsepower (597 kW). The older SD-400 uses direct current (DC) motors, while the newer SD-460 uses alternating current (AC) motors. The SD-460 also uses updated electronic equipment compared to the SD-400. On both types, electric current is received via an overhead catenary wire, which supplies 750 volts into the motors.

More than 80 SD-400 units were produced between 1985 and 1993, with all being manufactured at Siemens' primary manufacturing plant at its home base in Germany,[1] while nearly 70 SD-460 units have been produced since 1999, with all being manufactured at Siemens' secondary manufacturing plant at their American base in California as opposed to Germany.[2] The SD-400 is used by the Port Authority of Allegheny County for the Pittsburgh Light Rail in Pennsylvania, while the SD-460 is used for the Valencia Metro in Venezuela. Both types are also used on the St. Louis MetroLink operated by Bi-State Transit in Missouri.
