Rail passengers are being urged to check their journeys as safety checks are carried out on some Transport for Wales trains after a number of reported fires. There is a warning of reduced services on a number of routes as a result.
Services between Cardiff Central and Treherbert, between Carmarthen and Milford Haven, between Carmarthen and Fishguard Harbour and between Wolverhampton and Birmingham International have all been affected due to a shortage of train carriages.
Transport for Wales' chief operations manager Jan Chaudhry van der Velde said "safety was the number one priority". There have been reports of fires on some of the trains and safety checks are being carried out as a result.
