HST was built in the early 1980's as a petrol locomotive by Mardyke, and was run at a railway in Felixstowe. During the 2000's the locomotive was rebuilt as a Battery Electric locomotive with a 2hp motor. HST joined our railway in late 2013, and is now ready to enter full service during our 2015 season. This locomotive has a claim to fame of once being on television for an advert for British Rail!
