The weirdest thing like that I've ever seen was meeting a local that had an old EJ&E SD38 for power, freight, and an FRA passenger test and passenger car on the rear.
I have to say that is one ugly locomotive. But the old lightweight baggage car behind it looks interesting. I can just make out the old "Canadian Pacific" near the roof line, but I can't make out the word(s) below it near the bottom edge.
Consist was as follows:
68 Accommodation car (Ex-baggage)
424993 Restraint gauge measurement
63 Track Evaluation (Ex-buffet-solarium Antigua)
