166221 Reading Traincare Depot passes Blanchworth on 18 September 2021 with the 2O74 08:42 Gloucester to Weymouth GWR service. This is the highest numbered Class 166, and by a strange coincidence, just eight minutes later, the lowest numbered unit passed by in the other direction. To add to the coincidence, both DMUs are still in the old First Great Western blue livery.
