Transport for Wales (TfW) customers are being advised to plan their journeys carefully with services set to be disrupted from tomorrow by national industrial action. 

The National Union of Rail, Maritime, and Transport Workers (RMT) announced strike action will take place on Wednesday, July 27, and the train drivers' union, ASLEF, has announced its members will strike on Saturday, July 30. 

TfW is not involved in either dispute but its services will be affected, particularly on July 27, when the majority of services on the Wales and Borders network will be suspended. 

Wednesday, July 27 

The majority of rail services across the Wales and Borders network will be suspended as a result of the dispute between RMT and Network Rail, which means TfW will be unable to operate rail services on Network Rail infrastructure.  

An overview of TfW services: 

Wales and cross border services 

• The only services operating will be a Cardiff to Newport shuttle, with one train operating hourly in each direction, between 07:30 and 18:30. 
• Unfortunately, no other services will be able to operate. 

Core Valley Lines 

• Train services will operate between Cardiff Central and Rhymney, Treherbert, Aberdare and Merthyr Tydfil in an hourly service in each direction between 07:30 and 18:30. 
• Trains will be able to operate between Radyr and Treherbert, Aberdare and Merthyr Tydfil before 07:30 and after 18:30 (and then up to 20:30 due to engineering work). Road transport will enable customers to travel between Cardiff Central and Radyr in each direction outside of these hours. 
• However, customers are advised there will be extremely limited road transport capacity. 
• Customers are advised all train and road transport services are expected to be extremely busy due to the reduced service frequency. 

Note: This is a change from the three days of industrial action in June, when rail services started/finished at Radyr. 

There is also expected to be disruption on the days prior and after the industrial action. 

Thursday, July 28 

Due to the shift patterns of Network Rail's signallers and the significant challenges moving trains and crew to operate between strike days there is likely to be disruption. 

Customers are urged to check their journey before they travel. Online journey planners will be updated between two and four days before the first strike day. An overview as follows: 

Wales and cross border services 

No trains will run before 07:00 on all Wales and cross-border services. Services are likely to be much busier than usual – particularly the first services of the day. 

Core Valley Lines 

The first services of the day that depart Treherbert, Aberdare and Merthyr Tydfil will all be timed so they will be arriving into Radyr after 07:00. No trains will run before 07:00 on any lines except between Treherbert, Aberdare, Merthyr Tydfil – Radyr. 

No pre-planned road transport services will be in operation before 18:30 on Core Valley lines. 

Services are likely to be much busier than usual – particularly the first services of the day. 

Saturday, July 30 

• TfW will be running a full timetable but services are likely be impacted by strike action at other train operating companies. This could result in short-notice cancellations and changes. 
• Services from Swansea – Newport are expected to be very busy due to the reduced Great Western Railways timetable. Passengers are advised not to travel unless necessary. 
• TfW services Shrewsbury - Birmingham are expected to be very busy with the Commonwealth Games taking place and no services being operated by West Midlands Trains. Passengers are advised not to travel unless necessary. 

Existing tickets 

Customers with existing non-season tickets valid for travel on Wednesday, July 27 and Saturday, July 30 can use those tickets anytime between Tuesday, July 26 and Tuesday, August 2. Customers are encouraged to avoid travelling on Friday, July 29 and Sunday, July 31 as services are expected to be extremely busy. 

Alternatively, customers can claim a full refund, with no admin fee charged. Season ticket holders can apply for compensation via Delay Repay. 

In the meantime, we're suspending sales of Advance tickets for the strike dates in order to minimise the number of people disrupted. We're advising customers continue to check the TfW or Traveline websites, and those of other operators, for updates.
