66704 Colchester Power Signalbox passes Uffington on 7 February 2020 with the 6G04 05:15 Penrhiwceiber to Hinksey Sidings spoil train, with 66723 Chinook bringing up the rear. This is certainly the first time that I have photographed a train which originated from Penrhiwceiber (in the Welsh Valleys, between Mountain Ash and Abercynon)!
