43.172 isn't the first locomotive to commemorate those whose lives were sacrificed in war and it probably won't be the last. The power car was working 5Z70, an 09:37 Laira T&RSMD to Old Oak Common HSTD ECS past Brimpton Road, east of Thatcham, on 24 February 2016. Out of sight at the rear was 43.086.
