Here is a 37 Ton Shay. The cylinders, gear box, and motor are taken from a Bachmann HO 80 ton Shay. The trucks are from the Bachmann On30 Shay. The frame is scratch built from brass and the boiler, water tank, and cab are scratch built from sheet plastic and PVC tube and rod. The widest course of the boiler is a 1" PVC pipe coupling. The domes and boiler front are from Wiseman Model Services. The stack is from a Bachmann loco (they usually give you three with each loco)
