70811, 70812, 70803 & 66849 Wylam Dilly pass Challow on 14 May 2018, running as the 12:30 Hinksey to Tavistock Junction. The rear three locos were dropped off at Westbury, and although that operation didn't take long, it somehow managed to turn the 24 minutes late running here into being well over two hours late when it arrived at Tavistock Junction!
