Friday 29th September 2023:

An amended timetable will be in operation, in respect of the following:

• Planned MAJOR engineering works.
• Late notice critical engineering works.
• ASLEF industrial action (overtime & rest day work ban).

The railway is CLOSED between Princes Risborough and Aylesbury for 10 weeks between 19th August and 29th October inclusive. This is to facilitate HS2 civil engineering works including construction of a new bridge to carry the Chiltern line over the HS2 line.

During this period, rail replacement buses will operate as follows:

• Princes Risborough - Aylesbury.
• Princes Risborough - Monks Risborough - Little Kimble - Aylesbury.

Buses will connect with trains at Princes Risborough.

Additionally, due to late notice critical engineering works in the Aylesbury area, NO TRAINS will operate on the route Marylebone - Aylesbury Vale Parkway (via Amersham) between 10.00 and 18.00. During this period, rail replacement buses will operate as follows, connecting with London Underground services to/from Baker Street at Amersham:

• Amersham - Great Missenden - Wendover - Stoke Mandeville - Aylesbury - Aylesbury Vale Parkway.

In respect of industrial action, a slightly reduced service will be in operation. In particular, services may be subject to short notice cancellation.

Finalised timetables are uploaded into online journey planners 9 weeks before the date of operation. Please check your journey in the planner at the following link: https://buy.chilternrailways.co.uk/. Any journey checked outside of this timescale may be subject to change; please double-check how these amendments are due to affect your travel plans. For some engineering works and special events at Wembley Stadium, timetables may be released closer to the date of operation.
