Yes it was the overlap in time, that i was thinking about.
It was in a long shed, that as much as i can say really.
There was a set of BP coaches either side of D400 , & a driving car, in line with D400.
if that makes any sense. But thanks for the reply.
I just love any thing that as a time line so close .ie class 50`s along side steam,etc
did any one get a pic of a green western alongside a blue western, or did a new class 56 ever meet a wezzie?
i think you get the jist . I`m sure there are plenty of other close time lines between different locos.
