The Budd SPV-2000 is a self-propelled diesel multiple unit railcar built by the Budd Company in 1979–1980 for use on North American commuter railroads. The design was a successor to Budd's popular Rail Diesel Car (RDC) but based on the body of the Amfleet passenger car. It did not prove a success: Budd built 31 cars and they proved mechanically unreliable.
