Future of Cardiff Crossrail: Rail Innovations & Sustainable Transport Guide
Cardiff Crossrail, a new tram system, links Cardiff Central to Cardiff Bay. Funded by £100 million, it’s set to open in 2028, boosting Cardiff’s rail network.

Cardiff Crossrail: A Major Step Towards Modern Tram System for the Welsh Capital
Cardiff is poised for a significant transformation of its public transport network as ambitious plans for the Cardiff Crossrail tram system advance. This project, backed by a £100 million joint funding from the Welsh Government and the UK Government’s Levelling Up Fund, will initially link Cardiff Central station with Cardiff Bay, offering a modern and efficient transport solution for residents and visitors alike. The initiative aims to improve accessibility, boost connectivity, and encourage a modal shift towards sustainable travel. This article provides an in-depth analysis of the project, including its key phases, infrastructure upgrades, and the expected benefits for Cardiff’s commuters and the wider rail network.
Phase 1a: Cardiff Central to Cardiff Bay: Unveiling the Initial Stages
Phase 1a of Cardiff Crossrail, fully funded and the subject of the Transport and Works Act 1992 application, marks the project’s beginning. This segment encompasses a comprehensive redevelopment of the highway infrastructure around Callaghan Square to integrate the tram/train with the existing Cardiff Bay rail line. A new tram/train platform will be constructed at Cardiff Central station, enabling smoother transfers and enhancing passenger flow. Furthermore, the plans include enhanced pedestrian and cycling provisions, with a segregated cycleway linking Cardiff Central to Callaghan Square. This is a vital addition, reflecting the increasing emphasis on active travel modes. The project also involves modifications to traffic access on Bute Terrace and Lower St Mary Street, ensuring efficient traffic management in the area. The primary goal of phase 1a is to create a reliable, affordable cross-city tram service that links underserved communities to the rail network.
Infrastructure Upgrades and Design Revisions: Addressing Stakeholder Feedback
Following public and stakeholder consultations in autumn of the previous year, Cardiff Council has incorporated several key updates into the scheme design. These changes are aimed at addressing community feedback and optimizing the project’s impact. Key revisions include maintaining traffic access on the north section of Bute Street to ensure better road access between Butetown and Cardiff Bay. The council has also committed to ongoing engagement with access and inclusion groups throughout the detailed design process, ensuring the tram system is user-friendly for all. Furthermore, there are plans for additional planting and green infrastructure on Callaghan Square, improving the urban environment. Improved bus movements on Custom House Street and a replacement bus layover bay on Park Street have been factored in, showing a commitment to integrating various transport modes seamlessly.
Timeline and Key Milestones: A Roadmap to Operation in 2028
The project’s timeline is clearly defined, with a phased approach leading to operational services by 2028. The council is now seeking an order under the Transport and Works Act 1992 to authorize the construction and operation of the first phase. The timeline includes summer 2025 for commencement of enabling ground and site investigation works, late 2025 for completion of detailed design, and spring 2026 for the start of enabling highway and public realm works. Construction of the tram track and associated platforms at Cardiff Central is set to begin in late 2026, with all infrastructure works completed by 2028. A 42-day objection period will follow the application. If the Order is approved by Welsh Ministers, tram services are scheduled to be operational by summer 2028.
The Vision for Cardiff Crossrail: Transforming Urban Mobility
Cardiff Crossrail represents a long-term investment in Cardiff’s public transport infrastructure, designed not only to move people but to transform how they move. The tram system aims to connect underserved communities to the rail network, reducing reliance on private vehicles. The second phase, Phase 1b, extends the tramline from Cardiff Bay station through the Flourish and Pierhead Street area, although funding for this is currently not in place. The plan includes new pedestrian crossings and a segregated cycleway connecting Roald Dahl Plass to the proposed new indoor arena. The ultimate goal is a greener, more sustainable transport system.
Conclusion
Cardiff Crossrail represents a significant step forward in enhancing Cardiff’s public transport infrastructure, poised to improve connectivity and encourage more sustainable modes of transport. The project’s methodical approach, from securing funding to conducting public consultations and adapting designs, highlights the meticulous planning undertaken to deliver a comprehensive tram system. As the project progresses through its various phases and integrates stakeholder feedback, the implementation of the Transport and Works Act 1992 will facilitate crucial infrastructure improvements, including a new platform at Cardiff Central, segregated cycleways, and improved traffic management. The project’s alignment with the Cardiff Bay line transformation further demonstrates a commitment to modernising the city’s rail and urban transport networks. With the planned commencement of services by 2028, the people of Cardiff are looking forward to a more efficient, environmentally friendly, and connected city transportation system. The successful implementation of Cardiff Crossrail can set an example for other cities, showcasing the benefits of integrating rail infrastructure with public transport and urban regeneration initiatives.
