The Siemens SD-400 LRV is an electric light rail vehicle (LRV) built by Siemens-Duewag AG. It is powered by four individual Siemens DC-IBGT electric motors with each one developing 200 horsepower (149 kW) & creating a combined total power output of 800 horsepower (597 kW). Electric current is recieved via an overhead catenary wire which supplies 650 volts into its DC motors. The unit's frame is also built upon a A-B-C 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. Empty weight of each car is 89,560 lbs!

More than 80 SD-400 units were produced between 1985 and 1993, with all being manufactured at Siemens' primary manufacturing plant at their home base in Germany. The SD-400 is currently used by two transit operators, these are both the Port Authority as well as Bi-State Transit (MetroLink) in St. Louis, Missouri.
