The steam loco is based loosely on North American designs from around the 1890's, and uses wheels from Big Ben Bricks (Thank you, Ben!). It took me a few tries to get the clearance on the leading truck's wheels to allow the locomotive to go around the tight-radius Lego curves. The caboose is a heavily modified set #10014. It has been lengthened and widened (all my trains are 8-wide). If you have any questions or comments, I can be reached at "arjay at cox-internet period com"
