Railway lines around Rhondda Cynon Taf are due to be upgraded, with essential engineering and infrastructure works set to take place over Easter and continue into 2023.

Transport For Wales is carrying out a large-scale public transport upgrade across Southeast Wales to introduce Metro to the transport system. Metro will be an integrated network of bus, rail and active travel to improve connectivity and sustainable travel across South Wales.

A series of new signals, overhead line equipment for electric travel, bridge repairs, and track enhancements will take place from Easter.

Initial works are being focused on the Core Valley Lines, which run between Aberdare, Cardiff, Coryton, Cwmbargoed, Merthyr Tydfil, Rhymney, and Treherbert.

Certain Core Valley Lines will be closed for a brief period while these works are carried out, and a bus replacement service will be put in place to reduce disruption.

The closures include:

  • Radyr and Pontypridd between 14th – 19th April 2022
  • Abercynon to Aberdare between 17th April – 13th May 2022

For more information on the closures and the bus replacement services, TFW advise passengers to check their website before travelling.

Workforces will be carrying out the work during the day and at night, but have assured those affected by this that they will try to keep noise and disruption to a minimum.
