History
Chalfont & Latimer station was formerly served by steam–hauled Metropolitan line trains with a changeover to an electric locomotive at Rickmansworth. The electrification north of Rickmansworth to Amersham and Chesham was completed in 1960, with steam trains being finally withdrawn in 1961. British Railways took over the operation of the service north of Amersham at the same time, using Class 115 diesel multiple unit trains. The station had a goods yard, which closed on 14 November 1966.

From 1961, Metropolitan line trains at Chalfont & Latimer were formed of A60 and A62 Stock. Prior to 11 December 2010, the branch was served by a single four-car shuttle train (using Chalfont & Latimer station's bay platform), except for two through trains in either direction during peak periods. From 12 December 2010, the Chesham service now consists of half hourly direct services formed of eight car S Stock trains being introduced at that time. Chiltern Railways (Aylesbury-Marylebone) trains are formed by Class 165 and Class 168 diesel multiple units.

On the up, south-bound, platform there is one of the few surviving K8 telephone kiosks. Now used for the TfL internal system, the kiosk is Grade II listed
