I hate advertising liveries, most of which seem to be applied with little regard to the lines of the vehicle carrying them. Commemorative liveries often seem to be designed much more sympathetically, as is the case with 43.172, commemorating the fallen of World War I.
43.172 arrived at Reading with 1L92, the 18:29 Swansea - Paddington, on 29 May 2017.
