Get on board Class 74, rebuilt from the earlier Class 71 to deliver greater power – and line speeds of up to 100mph on the BR Southern Region.
The British Rail Class 74 Electric Locomotive is a Bo-Bo configuration electro-diesel engine rebuilt in a run of ten units from the earlier Class 71.
Re-engineered at British Rail Crewe Works in 1967 and 1968, they were returned for service on the BR Southern Region where they were able to run using third rail power, or from an on-board diesel engine.
Rebuilt with greater power than the original Class 71, the Class 74 units could reach up to 100mph on electric power and 60mph using its internal diesel engine. None were preserved at the end of Class 74’s working life in 1977-78.
