  • Modernising the Cardiff and Valleys' Railway

    The multimillion-pound scheme to modernise the south Wales railway includes upgrading seven key stations on the route

  •  Installing-a-new-platform 

    On schedule

    Better stations, better journeys

    As part of modernising the railway in south Wales, 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 have also built a new entrance building at the back of Cardiff Central station, which was opened in September 2015.

    Platforms and capacity

    Having more platforms at key stations will allow more trains to run, while longer platforms provide room for extra carriages at peak times. This will create the extra capacity needed for the rapidly growing number of people commuting to Cardiff by rail. The improvements will add hundreds of seats to services during the morning and evening rush hours.

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

    Improving Cardiff’s stations

    Wales' two busiest stations – Cardiff Central and Queen Street – cater for almost 12.5m passengers a year. This is 67 per cent of the total number of passengers using the valleys railway.

    Improvements we’ve made include:

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

    Energlyn station

    The new £5.2m station at Energlyn, near Caerphilly, opened in December 2013. Built with funding from the Welsh Government, the new station gives direct access to and from Cardiff to passengers using Energlyn and Churchill Park stations.

    Resignalling the railway

    Upgrading signalling is another important aspect of modernising the south Wales railway. We’re installing new signalling technology throughout the route. This will help to give passengers quicker, more reliable journeys – particularly after the route has also been electrified.

  • Better stations, better journeys

    We'll deliver improved stations with better accessibility  an essential component of a modern, fit-for-purpose railway.

    Additional platforms at a number of stations across the south Wales railway will accommodate more trains.

    Supporting businesses

    Extra train services will handle the increased commuting traffic into Cardiff.

    Improved reliability

    Resignalling the south Wales railway will improve reliability and reduce delays.


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