43035 speeds past Compton Beauchamp on 8 May 2016 with the 1B79 18:37 Paddington to Swansea GWR service. The soft evening light shows up the different shades of brickwork in the bridge. Presumably before the installation of the down relief line here, the bridge was of a symmetrical design. If so, that explains the different colour bricks of the parapet starting from the centre of the bridge, and the altered left hand arch.
