Power car Sc51043 is one of the batch of 23 Inter-City DMU "DMBSO" (Driving Motor Brake Second Open) cars built especially for Glasgow - Ayshire services in 1959.
It is fitted with two 150 h.p. AEC horizontal diesel engines, each of which drives a 4-speed epicyclic gearbox and a reversing final drive unit mounted on a bogie axle. Top speed is 70MPH.
BR DMU designs required that units could couple together for multiple working with control from the leading driver's cab. To achieve this, Inter-City units had control cables which ran the length of the train, with jumper connections between vehicles. Each power car has its own control air system, with electrically-operated pneumatic valves which control the engines in response to the driver's actions.
Sc51043 has been extensively refurbished by Midland Railway Enterprises of Derbyshire, as part of our Heritage Lottery Fund project. Engines have been overhauled by SRPS, and the car is being fitted out internally at Bo'ness.
