Thanks for the info Fatman. Sorry, here is a pic of the complete PLM train. It is hard to identify a lead car because the
two end cars appear identical. I believe the center unit on the 3 car trains was the powered unit. But having said that, I believe
any of the cars could have been powered as the frames are virtually identical. I am also enclosing a pic you might appreciate.
A "WELLS OF LONDON" SILVER STREAK. I actually got this in a lot I bought for another reason. When I did a bit of research
it seems it may be part of a british Mickey Mouse set.
