The story
Previously a railway junction and station where a branch to the town of Chard joined the main line. It was marked on a 1946 OS map (full revision 1930) as "Chard Road", the original name of the station, which was changed much earlier. It appeared as "Chard Junction" on a 1970 OS map (fully revised 1968), by which time the junction and station had closed.
