Cardiff and Valleys

We’re upgrading seven key stations on the South Wales route.

We’ve added or extended platforms at Cardiff Central, Cardiff Queen Street, Tir-Phil, Barry, Caerphilly and Pontypridd, and built a new station at Energlyn. We also built a new entrance building at the back of Cardiff Central station, which opened in September 2015.

The Cardiff and Valleys railway modernisation scheme is due to complete in 2017.

Platforms and capacity

Having more platforms at key stations allows more trains to run, while longer platforms provide room for extra carriages at peak times. These improvements create the extra capacity needed for the rapidly growing number of people commuting to Cardiff by rail. Hundreds of extra seats are now available to passengers during the morning and evening rush hours.

The funding for this scheme includes £17m from the Welsh Government.

Improving Cardiff’s stations

The two busiest stations in Wales – Cardiff Central and Queen Street – cater for almost 12.5 million passengers a year.

We’ve made the following improvements:

  • Cardiff Central: new platforms and facilities, and a modern entrance building on the south side
  • Queen Street: a new entrance and two new platforms – one north-bound and the other for Cardiff Bay services.


The work across South Wales will pave the way for the electrification of the Cardiff and Valleys lines in Control Period 6 (2019–2024).
