Shortages of trains and engineering work are continuing to affect Transport for Wales (TfW) train services, so anyone intending to travel on the network should check for the latest information before travelling.

The shortages of trains because a number of Class 175 trains have been withdrawn so that additional maintenance checks can be carried out following the recent discovery of some mechanical issues. As a result of the checks, some of the trains require further repairs to their engines before they can re-enter passenger service. These checks, with the resulting disruption to passenger services, are likely to continue into early April.

Although the problems lie with the Class 175s, disruptions are likely throughout the Wales and Borders network, as other trains are moved to provide capacity where demand is highest. It is especially important that customers check to ensure they have sufficient time before they travel, as first and last trains and any ferry connections may be affected.

The routes affected by the changes are:

• Newport to Crosskeys – service cancelled, and no rail-replacement bus services;
• Chester to Liverpool – service cancelled but tickets will be accepted on Merseyrail services;
• Conwy Valley Line – service cancelled, but rail-replacement bus services will be provided;
• Wrexham to Bidston Line – service cancelled, but rail-replacement bus services will be provided;
• Cambrian Coast – early morning Barmouth service cancelled, but rail-replacement bus services will be provided;
• Core Valley Lines – reduced service on some routes. No services between Pontypridd and Merthyr Tydfil until Monday, 3rd April due to transformation work for the South Wales Metro;
• West Wales lines – rail services have resumed;
• Milford Haven and Fishguard services west of Carmarthen – rail services have resumed.

Jan Chaudhry-Van der Velde, Chief Operations Officer at TfW, said: “The safety of our customers and colleagues remains our top priority.

“Our Class 175 trains will not be allowed into passenger service again until each train has had its engines checked and repaired, and has passed the relevant safety inspections. This programme of work is happening as we speak, at Chester depot, where these trains are maintained on our behalf by CAF Rail UK.

“An initial supply of materials is available for the repair programme, and further parts are being sourced from overseas to speed up the process. The position will improve each week, and the completion of the repair programme is expected to go into April.

“Whilst this leaves us with a temporary shortage of rolling stock, other fleets are being spread out across the Wales and Borders network, and timetables have been adjusted to try and impact the fewest number of passengers.

“We’re very sorry for the disruption to customers’ journeys while we carry out this essential work.”
