Class 108 (BR Derby General Branch Line and Local Services 2,3,4-car)

The Class 108 was the second of the so-called "Derby Lightweight" DMUs being a lot lighter in construction than other units like the Class 114. The Class 108 was designed for branch line and local services having a low-density interior and toilets and were allocated to British Rail's London Midland and Eastern Regions [1]. They served as 3 or 4-car sets, some later reverting to 2-cars, until the early 1990s. Some cars with first class accommodation were later declassified to second/standard [2].
