Services Since 12 December 2010, Chesham has had an 8-car train every 30 minutes direct to Aldgate. 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.

For Chesham residents this is a major improvement, as previously Chesham was served in the off-peak solely by a 4-car shuttle train to Chalfont & Latimer, where passengers had to change onto a train to or from Amersham. 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.
