37254 working 3Q34 over Landore Viaduct on NMT - Wednesday 10/04/2024

Colas 37254 working the Network Rail Measurement Train, seen just after 2200 on 10/04/2024 having come off Landore TMD heading to Swansea station, before heading the 3Q34 on to Milford Haven and return during the night.
I had just been to the Swansea.com Stadium to watch Swansea City beat Stoke City 3-0 and this was a nice surprise heading for the car to go home!
