A junction station was built at Rogiet to serve the new Severn Tunnel, that opened in 1886. This "Severn Tunnel Junction" station was in operation for tunnel works traffic by 1883 and as a functional station by 1885 although it is unclear if it was open to the public at this date, before the official opening of the tunnel in 1886. The sidings of the new station were built on the Caldicot Levels, using spoil excavated from the cutting into the tunnel. The name 'Rogiet Station' appears on several contemporary maps, although these are always in conjunction with a "planned" station, as the junction for the new tunnel line. There is no evidence for a station before this date, or for a constructed station ever having been called 'Rogiet Station'.
