Class & Prototype
- Class: British Rail Class 121
- Traction: Diesel Multiple Unit
- Built: 1960
- Total Built: 16
The British Rail Class 121 single-car DMU operated for 57 years from 1960-2017, making it Britain's longest-serving diesel multiple unit. Built by Pressed Steel Company, just 16 DMBS power cars served Western Region branches including the Greenford shuttle, Henley, Marlow, and Severn Beach line. Distinctive "antler" exhausts curving around illuminated headcode boxes set them apart from similar Class 122 designs. Originally AEC-powered, the fleet was re-engined with Leyland 680 units during 1971-1980. Following privatisation, units worked for Silverlink on the Marston Vale Line before Chiltern Railways' remarkable 2003-2017 renaissance extended their career. Twelve vehicles survive in preservation. Available as models from Bachmann (OO), Dapol (OO/N/O), and Heljan (O gauge) in numerous authentic liveries.
No prototype found.
