 The Metropolitan Railway Company's original plans drawn up in 1912 intended the line to continue through Cassiobury Park and beyond to Hempstead Road on an area known locally as 'The Wilderness', where West Herts College would later be built (opened in 1938).Watford Council had recently bought part of the Cassiobury Estate and objected to the proposed railway through the town park and recreation gardens, and so the last section of the route was removed and the line would end abruptly in Cassiobury Park Avenue instead.An opportunity arose in 1927 for another route to extend the line into the centre of Watford.
