Parry People Movers Ltd. (PPM) was a small British manufacturer of lightweight railcars that use flywheel energy storage for traction, allowing electric systems to operate without overhead wires or third rails. The company built one prototype and two production vehicles, the British Rail Class 139. It also designed concepts for trams and other rail technology using alternative fuels such as gas and hydrogen, but was not successful in finding further buyers among transport operators.[1]
PPM was founded and directed by John Parry, who died 17 February 2023,[1] and the company was liquidated later that year.[2]
