Mae amseroedd trenau ar draws Cymru a'r Gororau ar fin newid dydd Sul yma

13 Dec 2024

Rail passengers are being urged to check their journeys carefully as the most significant timetable change in decades takes place this Sunday (15 December).

The timing of nearly every service across the South Wales Mainline, the Marches Line between Newport and Shrewsbury, and on other routes across the Wales and Borders network will bring more consistency for passengers, with trains departing at the same time past the hour and from the same platforms.

The timetable changes have taken four years to develop and will see increases in the number of services on some routes and later evening services from Swansea and Cardiff.

Transport for Wales’ Planning and Performance Director Colin Lea said: “This is the most significant timetable change in a generation for mainline services. 

“We’ve invested £800 million in new trains and now is the time to really make the most of them. We’ve been working towards this timetable for four years and the consistency it will deliver will be a massive improvement for many customers. 

“While this is a major change, there are also big improvements planned for the North Wales Coast and Cambrian lines in the next 18 months with newer trains and capacity improvements.” 

Nick Millington, Network Rail Route Director for Wales & Borders, said: “This timetable change is going to be significant with faster journeys, more frequent train services and more seats across our network. 

“Our passengers depend on services to get them to where they need to go and these changes are all part of building a better, more reliable, and sustainable railway as we work in partnership with Transport for Wales to deliver the best for Wales & Borders.”

Notes to editors


Some key changes within the new timetable include: 

  • Significantly more stops at Pontyclun, Llanharan and Pencoed – increase in total daily services from 38 per day to 59. A 55% increase. 
  • Increase in Swanline services during peak hours to 1 train per hour (Baglan, Briton Ferry, Skewen and Llansamlet). 
  • Two extra Milford Haven services and a more evenly spaced service to Fishguard Harbour which removes a six-hour gap without trains during the middle of the day. 
  • The last train from Cardiff to Maesteg via Bridgend is now later - at 11:24pm. 
  • Later last train from Swansea to Cardiff leaving at 11:30pm Monday to Friday. 
  • More consistent departures with more trains leaving at the same time past each hour.  
  • Maesteg services towards Cardiff will now run through to Ebbw Vale, rather than Cheltenham Spa. 
  • Cheltenham Spa services will start and end at Cardiff Central. 
  • Instigation of the changes brought about by the Strategic Timetable Review on the Cambrian and Heart of Wales lines. 
  • Introduction of brand new Class 756 trains on the Core Valley Lines (starting November) and dedicated active travel trains with extra bike spaces, a full refit and a dedicated livery for the Heart of Wales line. 
  • Some changes to the calling pattern on certain services between Cardiff and Manchester Piccadilly, to speed up some trains and deliver a standard pattern in the timetable. 
  • Some local services between West Wales and Cardiff will now use Platform 0 at Cardiff Central. 
  • The North Wales Branches will continue to have 100% of journeys on new fleet and the North Wales Mainline with over 80% of journeys on new fleet. Overall, over 87% of journeys will be on new fleet for North Wales services from December 2024 timetable.  

Additional information

Across the UK rail industry there are two major timetable changes each year – in May/June and in December. 

£800 million has been invested in brand new trains with just over half now in service.  

We have completed the introduction of 56 brand-new Class 197 trains on the mainline (these trains will be introduced on the Cambrian line in 2025/26).  

In addition, from November 2024 we are starting to introduce brand new Class 756 trains on the Core Valley Lines. 

The Heart of Wales line is seeing the introduction of refurbished active travel trains during this timetable period, and these can transport up to 12 bikes, which we hope will help develop the line for leisure journeys in particular. 

TfW runs more than 1,000 passenger services per day Monday-Saturday. 

The reduction in a small number of services from the Cambrian and Heart of Wales lines was part of a Strategic Timetable Review carried out earlier this year. More details can be found HERE 

Mainline services are defined as all services Transport for Wales runs, excluding the Core Valley Lines around Cardiff.
