50024 Vanguard approaches Didcot North Junction on 9 December 1986 with the 1F27 09:40 Oxford to Paddington Network SouthEast service. Three times the number of coaches compared to an equivalent service today, and with comfy seats, and no engine rattling under the floor! Also, just about the perfect livery combination in my view, a large logo Class 50 with black roof and window surrounds, and red buffer beam, hauling a rake of blue and grey stock.
