Tring's Trains Productions's video: BR Class 110 DMU on the L HR Summer 2017 - 4K

The two-car class 110 diesel multiple unit (DMU) was part of an original fleet of 30 “Calder Valley” units built for British Railways (BR) in 1961 by the Birmingham Railways Carriage and Wagon Company Ltd. (BRCW) Having been built as three-car sets, the unpowered center trailer vehicles were withdrawn in the early 1980s, leaving only the driver car, each of which is equipped with two 180hp Rolls-Royce engines. The “Calder Valley” DMUs were regular performers on many lines on both sides of the Pennines, and were originally allocated to the Eastern and London Midland Regions of BR. The Lakeside & Haverthwaite set was aquired from Leeds Neville Hill depot, having been made redundant on the introduction of second generation ‘Pacer’ and ‘Sprinter’ DMUs.
