The station is on the London Marylebone – Aylesbury line and is served by Chiltern Railways trains.

When London Underground's Metropolitan line (the successor of the Met) was fully electrified in the late 1950s and early 1960s, a decision was made to run only as far as Amersham.

British Rail ran services until privatisation in 1996, when Chiltern Railways took over the franchise.

In 1989-90 BR's Network SouthEast refurbished the station and the "up" (London) platform canopy was shortened slightly.

Some of these are express services, which skip the stops shared with the Metropolitan line nearer to London.
