The distance between Chesham and Chalfont & Latimer is the longest between adjacent stations on the network, at 3.89 miles (6.26 km).
Although the MR continued to buy land between Chesham and Tring for some years after the station's opening, the route was never extended further.
The reasons for listing the station at this level were: Since 12 December 2010, Chesham has had an 8-car train every 30 minutes direct to Aldgate.
[18][19] In the morning and evening peak, trains run non-stop between Moor Park and Harrow-on-the-Hill, then calling at Finchley Road and all stations to Aldgate.
Although the reasons for the new service pattern were largely technical (the S8 Stock, while designed as two four-car trains, cannot be split into four-car trains as they have driving cabs only at the outer end of each unit), it was expected to ease congestion on local roads by increasing Chesham's attractiveness to park-and-ride commuters.
