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 1962.
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.
