The main entrance is covered by a polygonal metal canopy supported by twin Doric columns, and the interior, mostly unaltered from the original, is decorated with period tiling and hardwood panelling.

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).

Through a third party, the Metropolitan was able to purchase an existing building at 44 Watford High Street together with two-and-a-half acres of backlands, with the intention of creating a terminus in the town centre.

[10] The possibility of a single-track extension in tunnel—either from the existing station or following a diversionary route around the station—was explored, but costs were extremely high and no Parliamentary powers were sought.

The High Street building was leased out and was eventually disposed of by London Transport in 1936,[19] and today Watford station remains the terminus of the line, approximately one mile from the town centre.

[29] A report compiled in 2012 by the transport watchdog London TravelWatch concluded that the opening of new stations on the route would mitigate any inconvenience caused by the closure, and that a minority of passengers would experience an increase in journey times of more than 15 minutes.
