That’s not a BigBoy. The Bigboys were articulated, and had two sets of drivers. The locomotive you have there is a 4-8-4, with only one set of (8) driver wheels. It’s big, no doubt, but it’s not a Bigboy.

My bad.Here is a pic of a BigBoy in action.Note the Dual Drivers(4-8-8-4)

They were used to haul freight not passengers.
