On leaving Doncaster on 18/05/2022 I saw three mustard coloured items of OT plant one of which I believe was a Rail Delivery Train? I took a couple of photos through my trains double glazed window at speed and thus the identifying numbers are blurred. One of the RDT's seemed to have a crane jib attached to it whilst the other two did not! Are the latter two "Shute Wagons"?
I'm looking for the numbers of these items, if anyone can assist I'd be very grateful. I am relatively new to this hobby so any help is going to be really appreciated.
