Sounds to me as if someone did a limited amount of historical background research, then muddled that in with the current day information, ending up with a real mish-mash of inaccuracies. I think that a lot of the "tour trains" are more for the well-heeled traveller than for railfans, so historical and factual accuracy play a minor role for most riders.

These were freight trains, and channels like Discovery and History usually do a little better, although not all the time.

I'll chalk it off to more hype about diesels.
