Derby Lightweight

The UK's first proper DMUs. The sets met with huge success, starting a trend of greatly increasing passenger figures which most first generation DMUs continued.

In all 219 vehicles were built (including the two bodies that became the battery unit), working on all regions except the Southern.

Later builds of DMU had a more advanced control system meaning these sets were non-standard and destined for early withdrawal, with the last withdrawn from passenger use in 1969.

Some vehicles saw departmental use, and three cars survive in preservation.
