Information
The British Rail Class 769 Flex is a type of diesel electric multiple unit (DEMU), Bi-mode Multiple unit (BMU) and Tri-mode multiple unit (TMU) which is currently being converted by Brush Traction, and running in service with Transport for Wales Rail Limited. The train is a conversion of the existing Class 319 electric multiple unit (EMU), a conventional unit type which had become surplus to requirements during the 2010s.

The conversion process is carried out by a partnership between the rolling stock leasing company Porterbrook and train manufacturer Brush Traction. The conversion principally involves the addition of a pair of MAN diesel engines (one under each driving trailer vehicle), the output of which is fed into ABB-provided alternators to power the existing electric traction systems. According to Porterbrook, the Class 769's performance under diesel power is either equal or superior to that of a Class 150 Sprinter diesel multiple unit (DMU), and the switchover between EMU and DMU modes can be carried out while the train is in motion.
