This was done in Canada. When I was a lad, Dad moved us to Roseville, CA. Now, today you would not know it but once Roseville was the major hub of trains crossing the Sierra Nevada. It had a large roundhouse (now gone) and serviced the train we called, incorrectly, as Malley's. They were actually a Baldwin Cab Forward. https://en.wikipedia.org/wiki/Southern_Pacific_4294 These Cab forwards were giants. I think some locomotives were actually larger, but they too were giants. However check out this steam locomotive in Canada. [video=youtube;HLjZEZQklkY]https://www.youtube.com/watch?v=HLjZEZQklkY[/video]
