The Cardiff Crossrail project is moving forward with Graham Group leading its initial phase.
- Graham Group, in collaboration with Cardiff Council and Transport for Wales, will spearhead the design and construction of a new tram-train system in Cardiff.
- With £50M funding each from the Welsh and UK governments, the project aims to establish a vital rail link from west Cardiff through Cardiff Bay.
- The initial phase focuses on developments from Cardiff Central to Cardiff Bay Station, with significant infrastructure upgrades.
- This transformative project promises to enhance transport connectivity and create employment opportunities in the Welsh capital.
The ambitious Cardiff Crossrail project has entered a new phase with Graham Group appointed to lead its design and build. This decision follows a detailed tender process, and the project aims to establish a rapid transit tram-train system linking west Cardiff with the Cardiff Bay area. This new system will connect to the future Cardiff Parkway station on the South Wales Main Line, providing enhanced transport links for the region.
The Welsh and UK governments have each committed financial support of £50 million, ensuring the project’s viability. Graham Group will work under an Early Contractor Involvement (ECI) agreement, joining forces with Cardiff Council and Transport for Wales (TfW) to manage design and construction efficiently. The collaborative approach is expected to streamline costs and optimise construction methods.
Phase 1a of the Crossrail project includes a comprehensive redevelopment from Cardiff Central to Cardiff Bay Station. Critical changes will take place around Callaghan Square, where the tram will integrate with existing rail lines. Additionally, a new tram/train platform is set to be constructed at Cardiff Central, coupled with a series of pedestrian and cyclist-friendly measures. These will involve a segregated cycleway and improved traffic access on Bute Terrace and Lower St Mary Street, enhancing urban mobility.
Phase 1b, which remains pending funding, plans to extend from Cardiff Bay Station to Pierhead Street. This phase targets reconfigurations of the road network around the Flourish and Pierhead Street, and promises additional pedestrian and cycling paths connecting Roald Dahl Plass and the new indoor arena development.
Cardiff Council has welcomed the funding confirmation, highlighting its importance for the project’s progression. Council and TfW input will aim to maximise the project’s social benefits, including job creation, apprenticeships, and training for local residents. The detailed design is anticipated to conclude by Autumn 2025, with construction commencing later that year and completion projected for early 2028.
A new two-platform station will be established at the southern car park of Cardiff Central railway, facilitating easy interchanges. The tramway will traverse through Callaghan Square to the current Cardiff Bay line, while Cardiff Bay station will gain an additional third platform. Enhancements to public spaces along the tram routes are also planned, linking communities and key destinations within the city.
The Cardiff Crossrail project exemplifies a significant step forward in enhancing urban transit and connectivity in Cardiff, promising to benefit its communities substantially.
