UPDATE: August 2026: 45149 

45149 was stopped over the winter for repairs and maintenance, with a B exam completed during April. The loco is still suffering some electrical problems, which delayed its entry to traffic. However it worked services at the end of June and is pictured below at Toddington on 5th July, working a train from Cheltenham. The loco took part in the Diesel Gala in late July and has worked numerous other days during the summer.
