Passengers are being advised of more engineering work between Cardiff Central, Barry and Penarth.
The planned infrastructure work means no train services will operate through the Vale of Glamorgan throughout Sunday, with replacement bus services running instead.
To help maintain connections, Transport for Wales will provide replacement buses between Cardiff Central and Penarth, as well as between Cardiff Central and Barry Island.
Under the temporary timetable, one bus per hour will run between Cardiff Central and Penarth. A more frequent service will operate between Cardiff Central and Barry Island, with two buses per hour serving passengers along the route.
Anyone travelling is encouraged to allow extra time for any journeys, as replacement bus services may take longer than normal train services. Those intending to travel should check journey planners before setting off and pay close attention to signage and staff instructions at stations.
The disruption is expected to last for the whole of Sunday, after which normal train services are scheduled to resume once the engineering work has been completed.
Replacement Bus Services
- Cardiff Central ↔ Penarth: 1 bus per hour
- Cardiff Central ↔ Barry Island: 2 buses per hour
