CrossCountry
CrossCountry will operate an amended timetable from Sunday, 14 December 2025 until Monday, 26 January 2026 on its services linking the South West, Reading and Birmingham through to Yorkshire, the North East and Scotland. This is because of Trans-Pennine Route Upgrade engineering work near Leeds.
- The hourly service between Plymouth / Bristol Temple Meads / Birmingham New Street and Scotland will be rerouted via Doncaster.
- The two-hourly Reading – Newcastle service will be rerouted via Wakefield Westgate, starting and terminating at Leeds.
Once the Transpennine Route Upgrade work east of Leeds is complete, CrossCountry will operate a normal service, notwithstanding amended timetable changes because of planned engineering work elsewhere on the network.
However, the 14:28 Birmingham New Street to Newcastle and 18:33 Newcastle to Birmingham New Street will be phased into the timetable in Spring 2026.
Govia Thameslink Railway
For Thameslink and Great Northern customers, this means that:
- A 08:45 from Letchworth to London King’s Cross and a 16:54 service from London King’s Cross to Cambridge are expected to be introduced early next year. The date of their introduction will be confirmed in 2026.
- The 16:27 London King’s Cross to Letchworth will be extended to Cambridge until the 16:54 London King’s Cross to Cambridge is introduced to give similar arrival and departure times for stations north of Letchworth.
The deferral of these two services is designed to reduce the congestion on the Welwyn Viaduct at the busiest times, minimising the potential for conflict and knock-on delays with other services operating on the network.
The changes being introduced this December will deliver more peak time services will run between London King’s Cross, Letchworth and Cambridge than operate today, meaning more room on trains for customers on this route overall.
