Gupworthy (sometimes referred to as "Goosemoor") was originally intended as an intermediate station on the West Somerset Mineral Railway (WSMR), but neither the proposed extension to Heath Poult nor that to Joyce's Cleeve was built, leaving Gupworthy as the line's southwestern terminus. The WSMR was built primarily to carry iron ore from mines to Watchet harbour in Somerset, England. The line was unconnected to any other, though it passed under what is now the West Somerset Railway south of the village of Watchet. The station was located west of the top of the line's most striking feature - a three quarters of a mile, rope-hauled incline at a gradient of 1 in 4 (25%).
