There's a partially restored Big Boy at the Forney Transportation museum in Denver, CO, that's worth the price of admission. I'm not a train nerd, but I did take Thermodynamics in college. The Big Boy is fantastically interesting with even a little knowledge of thermo, or kinematics. I can recommend a book "How Steam Locomotives Really Work" to see how steam locomotives really did work. Don't know if the book contains the truth, but if it's BS the authors went to a lot of work to make something so convincing.
