Our timetable is changing

Our new timetable starts on Sunday 18 May 2025

The Chiltern Railways May 2025 timetable starts on Sunday 18th May 2025 and has few changes, when compared to the previous timetable.

A small number of services have had their times changed by a few minutes with the aim of improving overall punctuality. Customers should check journey planners to see if their train is affected.

The main changes relate to some changes made during the busiest times on Saturdays, to provide additional capacity for customers on our trains.

Weekdays

• Tuesday - Thursday only

  06.38 Oxford-Marylebone will now be making an open call at High Wycombe at 07.26 – previously this trains was set down only. This train will now appear in online journey planners and will show on station departure screens at High Wycombe.

Saturdays

This is where we see the biggest set of changes, with the introduction of three new trains in the timetable aimed at relieving the pressure on the heavily used Birmingham line trains.

The three additional trains are 1H28 0946 Banbury-Marylebone, 1H30 10.13 Banbury-Marylebone and 1U51 1737 Marylebone-Banbury running in the evening.

• 1H28 calls at Bicester North-Haddenham & Thame Parkway-High Wycombe on its way to London and is aimed at relieving 1H27 0819 Stourbridge Junction-Marylebone, which no longer calls at either Bicester North or Haddenham & Thame Parkway.
• 1H30 calls at Kings Sutton-Bicester North-Haddenham & Thame Parkway-High Wycombe-Gerrards Cross-Denham-Wembley Stadium on its way to London and is aimed at relieving 1H30 0913 Birmingham Moor Street-Marylebone, which no longer calls at Kings Sutton-Bicester North-Haddenham & Thame Parkway and is non-stop from Banbury to London.
• As a result of 1H30 running, 1Y30 1015 Oxford-Marylebone is no longer booked to call at Gerrards Cross-Denham-Wembley Stadium, which means that after leaving High Wycombe, it calls at Beaconsfield and Seer Green & Jordans only before running non-stop to London.  The local Aylesbury-Marylebone train will preserve the connectivity between Beaconsfield and intermediate stations to London. The changes mean that customers at Seer Green & Jordans will see the 1110 departure to London running non-stop.
• 1U51 is booked to run non-stop from London to Beaconsfield, which means that Beaconsfield call comes out of the slightly off pattern 1T51 1746 Marylebone-Oxford service.

• The 2221 Birmingham Moor Street-Banbury is lengthened from a 2-carriage train to a 5-carriage train.

• Online journey planners
• Our online and pdf timetables (available from 25 April 2025)
• Posters displayed at impacted stations, four weeks before until four weeks after the changes take effect.
