Train strikes in the coming weeks will impact Transport for Wales services despite it not being in dispute with the National Union of Rail, Maritime, and Transport workers (RMT).

The RMT has announced that strike action will take place on Tuesday 21 June, Thursday 23 June and Saturday 25 June, which will significantly disrupt the rail network across the whole of the UK.

Transport for Wales (TfW) is not in dispute with RMT but the industrial action resulting from the dispute between RMT and Network Rail means TfW will be unable to operate rail services on Network Rail infrastructure.

The majority of rail services across the Wales and Borders network will be suspended, with the exception of services on the Core Valley Lines (CVL) north of Radyr in South Wales.

There is also expected to be disruption in the days prior to and after the industrial action. Transport for Wales has said that they will release more information as soon as possible.

Customers with existing tickets for travel from Monday, June 20 to Sunday, June 26 can use those tickets anytime between now and June 20. Alternatively, customers may claim a full refund by contacting

In the meantime, Transport for Wales are suspending sales of Advance tickets for the first three strike dates to minimise the number of people disrupted. Customers should continue to check the website, and the websites of other operators, for updates.
