43172 Harry Patch - The last survivor of the trenches brings up the rear of the 1B28 11:45 Paddington to Swansea GWR service at Grove on 12 July 2018. This kind of picture is more difficult to get right than an approaching shot, especially when it is travelling at 125mph. After noting that 43172 was on the rear, I just kept firing at ten frames per second as the back of the train went by!
