Between Carmarthen / Swansea and Shrewsbury

TOC(s) affected
Transport for Wales

The Heart of Wales Line is currently closed between Llanelli and Llanwrtyd. This is due to the ongoing repairs to the track following the derailment of a freight train near Llangennech.

How is this affecting the train service?

Trains are unable to run between Llanelli and Llanwrtyd.

Network Rail is working around the clock to complete the considerable repairs needed. The line is not expected to reopen until April 2021.

Alternative travel options:

Replacement buses:

Buses and minibuses will replace trains between Swansea and Llanwrtyd, from Monday to Saturday. The buses will be extended to run between Swansea and Llandrindod on Sundays.

For those stations with minibus-only access, customers may be required to change between larger buses and minibuses. A full size coach will operate a limited stop service and a minibus will serve all stations.

For helpful advice if you need to travel on a rail replacement service, including accessibility information, please use this page.

You can find the location of your bus replacement by checking station signs or by searching for your station on our station information pages.

Alternative route:

Tickets routed via the Heart of Wales Line will be accepted on alternative Transport for Wales rail services via Cardiff Central and Hereford, either directly or connecting into or out of planned replacement road transport.

What happened?

On Wednesday 26 August, a freight train transporting diesel fuel derailed and caught fire in the Llangennech area. The remaining diesel from the wagons has been removed and the damaged wagons have all been removed from site by road. Network Rail are now repairing damage to the rail infrastructure. Regular updates from Network Rail can be found here and a short video can also be viewed here.

Also in August 2020, extreme weather resulted in damage to the railway in various locations between Llandrindod and Craven Arms. Repairs on this section of the line were completed in November 2020 and trains are able to run again between Llandrindod and Shrewsbury.
