56104 brings up the rear of the 4Z03 08:00 Okehampton to Chaddesden Sidings rail grinder move at Standish Junction on 13 January 2018. The sunshine was an unexpected bonus on a largely cloudy day. 50008 Thunderer is leading the train. At Gloucester the train reversed, and then almost immediately 56104 failed, so Thunderer had to run round and take the train forward.
