The Budd Rail Diesel Car

Welcome! This is an unofficial website providing information on the Budd RDC, the classic North American streamlined self-propelled passenger rail car (aka Diesel Multiple Unit/DMU) built by the Budd company of Philadelphia between 1949 and 1956. A number of these magnificent first generation DMUs are still in service today across North America, while others are used on tourist lines or displayed in museums.
Read on for more information on these rugged and resiliant machines that sought to slow the decline of local passenger rail services in North America.
