The Budd Company unveils its first SPV-2000 self-propelled railcar in Philadelphia, Pennsylvania.

The Budd Company was a 20th-century metal fabricator, a major supplier of body components to the automobile industry, and a manufacturer of stainless steel passenger rail cars, airframes, missile and space vehicles, and various defense products.

The Budd SPV-2000 is a self-propelled diesel multiple unit railcar built by the Budd Company between 1978 and 1981 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.
