Transport for Wales is warning passengers to expect continued disruption on services between Hereford and Shrewsbury today.
It's after a train hit a tractor on a farm crossing near Leominster yesterday morning.
A man was airlifted to the hospital in Hereford, but his injuries are not believed to be serious.
A 32-year-old man from Bromyard has been arrested on suspicion of endangering safety on the railway.
British Transport Police said enquiries are continuing.
In a statement, TfW and Network Rail said: "Replacement road transport remains in place between Hereford and Shrewsbury and tickets will be valid for use with other operators via all reasonable alternative routes as well as with Stagecoach bus."
A further update is expected at midday.
