Man Powered Pump Trolley at Buckinghamshire Railway Museum


 Pump trolleys were used for inspecting the track. Built by the Sheffield Car Co., Three Rivers, Michigan, USA, this inspection pump trolley was probably built in the 1920s to their model 45 design of not earlier than 1889. It is the same type as features in older American Westerns and "The Great St Trinians Train Robbery" film. It is propelled along the track by pumping the handle up and down like a see-saw
