Network Rail is taking this incident very seriously and a detailed investigation is already underway. We are grateful that none of the staff and passengers on the train was hurt. We are working closely with British Transport Police, Arriva Trains Wales and the Office of Rail Regulation (ORR) to understand the sequence of events that took place.
We believe the cows entered the railway via a footpath level crossing where repairs had been conducted within the last few weeks. The train has now been re-railed and moved to another location, where it will be inspected by the ORR. The line is expected to be re-opened ready for scheduled services on Sunday afternoon.
