I was on a northbound 91 in this. They were routing everything through the Down Passenger Loop. The power must have been on, as we stopped at Retford (not for pickup or anything, we just stopped), before accelerating again. I was pretty impressed with the fact we only had 62 mins delay by the time we got to Durham.
The train that took the wires down was only just out of Retford station, with the contact wire draped all over the DVT. They were just about to couple a 67 to it when I passed.
