May TT 23 Static

Chiltern Railways customers reminded that all train times change from 21 May

Chiltern Railways has reminded customers that every train time will change from Sunday 21 May, when the May 2023 timetable comes into effect. The operator is urging customers to check before they travel as their usual journeys may not be the same. 

Chiltern’s May 2023 timetable changes reflect the ongoing rail recovery, changing commuter patterns and a boom in weekend leisure travel. In collaboration with Network Rail and neighbouring train operators, the new timetable builds on the data-driven capacity improvements made in December 2022.  

The timetable update also provides customers with regular departure times throughout most of the day that are easier to remember, and improved connectivity across the Chiltern network.  

Additional peak capacity has been maintained on a Tuesday, Wednesday and Thursday, with further increased service frequencies in the West Midlands on key commuter routes in collaboration with West Midlands Trains. This means that a regular, 15-minute service will be in operation between Dorridge and Birmingham Moor Street.  

Short-term alterations to the new timetable will be in place until 10 June to support the ongoing enhancement of services between Oxford and London due to the closure of the Nuneham Viaduct. 

All of the changes in Chiltern’s May timetable are designed to put carriages and services where they are needed most throughout the week based on customer demand, with the aim of improving customer experience, connectivity between stations and the reliability of service.  

Due to every train time on the network changing, Chiltern Railways is urging customers to triple-check their journey before they travel.
