Idmiston Halt railway station served Porton Down military camp in Idmiston, Wiltshire, England, from 1943 to 1968 on the West of England line.
History The station was opened on 3 January 1943 by the Southern Railway. It closed on 9 September 1968. The station had two platforms and a photograph taken in the early 1960s shows a building, seemingly constructed of breeze blocks, at the London end of the Down (westbound) platform that may have served as a booking office and a separate waiting room; a man in railway porter's uniform is standing outside.
