Stay Updated on Major Train Line Disruptions in Wales Due to Essential Upgrades Stay informed about significant train line disruptions in Wales caused by essential infrastructure upgrades.

Topics covered
In a significant move to enhance railway infrastructure, a major train line in Wales will undergo an 11-day closure, impacting services between Port Talbot Parkway and Swansea. This disruption is scheduled from January 26 to February 6, along with an additional closure on February 8.
These changes are part of essential refurbishment work carried out by Network Rail. Passengers should prepare for bus replacements, as the upgrade work will take place near the Landore Viaduct, located close to the Swansea Football Stadium.
The purpose of this closure is to ensure that the railway remains safe and reliable for both passenger and freight services.
The upgrades will involve the renewal of key components such as rails, sleepers, and switches, in addition to refurbishing the Landore Viaduct that crosses the River Tawe. This project is crucial for maintaining and improving the overall resilience of the railway network.
Implications for train services
During the closure periods, several train services operated by Transport for Wales and Great Western Railway will be significantly affected. Notably, Great Western Railway services linking London to west Wales will operate from Port Talbot instead of Swansea, necessitating amended timetables. This adjustment is essential to ensure that passengers can still reach their destinations despite the disruption.
Key service alterations
Travelers should be aware of the changes in the schedule, particularly for those using the Heart of Wales Line. Services will continue to operate to and from Carmarthen, albeit with some adjustments on January 27. Further changes will be made to the services connecting Llanelli to Carmarthen and onward towards Milford Haven, Pembroke Dock, and Fishguard Harbour, ensuring that all affected routes are accommodated.
Bus replacement services
As trains are replaced by buses during this maintenance period, passengers will need to familiarize themselves with the bus routes serving as alternatives. Replacement buses will operate between Port Talbot and Swansea, as well as between Cardiff Central, Bridgend, and Swansea during the weekends of January 31 – February 1, and again on Sunday, February 8. Additionally, Maesteg services to Cardiff will make stops at all local stations along the route to ensure accessibility for all travelers.
Planning ahead
Passengers are strongly encouraged to check their travel arrangements in advance. Journey times may be extended, and connections may differ from the usual schedules. Relevant updates can be found through the Transport for Wales website, the TfW app, and national rail information platforms. This proactive approach will help minimize inconvenience and allow travelers to navigate the temporary changes effectively.
Colin Lea, the Planning and Performance Director at Transport for Wales, expressed gratitude to customers for their patience during these vital improvements. He emphasized that these works represent a significant investment in the future reliability of the railway network, which is essential for both the commuting public and freight operations.
While the temporary closure of the train line may cause some disruption, it is a necessary step towards enhancing the safety and reliability of rail services in Wales. Passengers are urged to stay informed and plan their journeys accordingly to adapt to the changes.
