Buy or rent the 1939 classic movie "Union Pacific." It features extensive footage of the Bowker in operation, along with other V&T steamers, and should give you an idea of the kinds of trains this loco can pull. You can also see the Bowker rolling down a snowy mountainside (actually a scale model for that scene). This movie led me to get a Bowker model when I was a kid. I still have it, albeit in pieces after an aborted repainting effort.
