Chiltern Railways to add extra carriages to busiest services in May timetable

From Sunday 15th May, a new timetable comes into effect across the Chiltern Railways network.

As rail passenger numbers continue to recover, now surpassing 75% of pre-pandemic levels, pressure has been placed on commuter services arriving into London during peak times.

Since the last timetable update, Chiltern Railways has been continuously monitoring passenger levels and taking customer feedback on overcrowded services into consideration, ensuring that this update provides more carriages to key services that have previously been at risk of overcrowding.

As Chiltern uses all of its available rolling stock, some lesser-used services have been shortened to reflect passenger demand, while still ensuring that all passengers have a comfortable journey.

Improvements (Monday-Friday)

  • The 06:10 from Birmingham Moor Street to Marylebone will be extended to a six-carriage service (around 70 extra seats).
  • The 06:22 from Bicester North to Marylebone will be extended to a six-carriage service (around 100 extra seats).
  • The 06:33 from Birmingham Moor Street to Marylebone will be extended to a four-carriage service (around 70 extra seats).
  • The 06:43 from Oxford to Marylebone cannot be further extended from six carriages, however, a train starting at High Wycombe (07:21) will aim to relieve pressure on this service, which is currently our busiest. Platform announcements at High Wycombe and Beaconsfield will encourage customers to board the new service.
  • The 07:43 from Oxford to Marylebone will be extended to a five-carriage service (around 90 extra seats).

We monitor crowding levels on every service, and the formation changes in this new timetable have been calibrated to relieve pressure on 'pinch-point' trains. We will continue to monitor crowding levels, and will make further interventions where we are able to do so.

Minor changes to departures (Monday-Friday)

  • The 22:04 service from Marylebone to Oxford will now depart at 22:01 and now calls at High Wycombe to relieve pressure on the 22:10 Marylebone to Birmingham Moor Street.
  • The 22:13 service from Marylebone to Aylesbury will now depart at 22:11.
