Amersham and Chesham Area Bus, Tube, Train Times Pocket Guide (Area B1)
Also, we have a new Amersham & Chesham Pocket Guide. This A5 booklet contains all bus timetables for the areas in question, and a combined tube/rail timetable showing Chiltern Railways and the Metropolitan Line. You can also find the Amersham & Chesham map in the centre, by courtesy of Buckinghamshire County Council.
This one is up-to-date to the 21st May 2017 train/tube changes.
