Rickmansworth station

Rickmansworth is a London Underground (LU) station in the town of Rickmansworth, in the Three Rivers district of Hertfordshire to the north-west of London. It is served by the LU Metropolitan line and by Chiltern Railways. It is one of the few stations beyond Greater London served by the London Underground, and as a consequence is in Travelcard Zone 7, previously Zone A.HistoryUntil 1961, Rickmansworth station was the changeover point from steam to electric locomotives for Metropolitan line trains from Aylesbury to London. The electrification was then extended north to Amersham and Chesham, leaving Aylesbury services to be served by British Rail Class 115 diesel multiple unit trains (since replaced by Chiltern Railways Class 165 and Class 168 units). Locomotive hauled trains (steam and electric) on the Metropolitan line were then replaced by the new trains of A60 and A62 Stock.However, Rickmansworth is still the changeover point for drivers on the Metropolitan line. The majority of LU trains heading north to Amersham are timetabled to stop at Rickmansworth for about five minutes to change train staff. It is also the headquarters of the operational side of the northern section of the Met: It controls signals on the line from Northwood in the south to Watford/Chorleywood in the north and is one of the few locations on the Met where train drivers are based.
