An opportunity arose in 1927 for another route to extend the line into the centre of Watford. 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. 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, and today Watford station remains the terminus of the line, approximately 1 mile from the town centre.
