Great Western Railway's power car 43189 is on the rear of a train descending the steep hill at Exeter Central station. It is on a train from London Paddington that was diverted off its usual route at Castle Cary because of engineering work in Whiteball Tunnel, but it will soon be back on its own track when it reverses in Exeter St Davids station at the bottom of the hill.
