The Class 111 DMUs were based on Class 101/2s, but with different engines. The only external body difference was on the final batch of cars where a four character headcode box was fitted above the front cab windows, with the destination indicator on top of a reduced height centre window.
History[]
The first cars built, part of an order for 339 Metro-Camm cars, were 4 power/trailer sets for the LMR Manchester area built in early 1957. One of these was equipped with supercharged Rolls-Royce C6SFLH 230 hp 6-cylinder engines. This was followed by ten 3-car sets comprising DMBS/TSL/DMCL for the NER at Bradford, then a further twenty 3-car sets.[1] The type lasted in service until 1989 when the class was withdrawn.[2]
Technical details[]
- Coupling Code: Blue Square

Preservation[]
One car survives, buffet 59575 currently operational at the Great Central Railway. It operates as the centre car between two Class 101 power cars.[3]
