The Rail Adventure power cars were used to move old HST stock and are seen in the dark at Cradley Heath. One of the power cars is bowled by a DMU, I couldn’t read the numbers so not sure which were filmed. The workings were 5Z25 & 5Z26 stock moves from Laira to Chaddesden sidings. The Voyagers were working 1E67 Plymouth – Leeds, other was 1V66 Edinburgh to Plymouth. Numbers were 220023 on the first set and 221139+220002 on the other.
There is only a video for this as photos not very good quality in the dark, watch the YouTube video from the image below.
