Background information:
Major rail upgrades as part of the South Wales Metro will be taking place this summer to deliver faster and more frequent services.
The extensive work will require a two-week closure across the Treherbert line and a one-week closure on the Aberdare and Merthyr Tydfil lines.
The closure will allow Transport for Wales to carry out rail upgrades; relaying track at Pontypridd station, track and drainage improvements on the Treherbert line, and level boarding at Pentre-Bach station.
Project information is available on the Transport for Wales website.
