I haven't seen/noticed this before but then I may not have seen early close-ups of the cabsides. Maybe this was a requirement for US manufactured locomotives that had to be on the loco prior to export? Did it run with this in the grey & yellow livery , at least until the filler pipes fell off?
Actually it won't technically go with anything but modern DMUs etc and other preserved liveries such as MM 0141A. I'm presuming for a start that it will retain the modern LED marker light clusters. Will it have any RPSI markings?
2 Foot rule, yes you could run them together but then they rarely if ever ran in consist in this livery, nor in BnT
I'm not knocking the model, I've ordered one.
