"> There he is! His name is Boomer and he carries road number 9. Hes a 6 ton 2 foot gauge gas electric/mechanical locomotive in 7/8 scale. this is the 2nd locomotive I have built using a Delrin Chain and Sprocket mecahnism. I also discovered that its possible for the trucks to pivot a bit. another interesting note on this critter is that its the first one to utilize resin castings! The truckframes, counterweights, siderods, and pilots are all cast in molds that I made from my own patterns!
