As I understand it, the Heisler has rods driving the wheels on each truck (gear drive to one axle then coupled with rods, cylinders are inclined under the loco) while the Shay has gearing connecting all axles (and the drive system is all on one side with vertical cylinders). The Climax seems to have driveshafts to each truck and a different cylinder arrangement - inclined alongside the boiler. I'm guessing they were designed to be just different enough to avoid infringing patents - they're all "variations on a theme". If you go to www.walthers.com and search for the three names you'll find photos - that's where I found this information. I've wanted one of the HO scale ones for ages but the price is a bit high for me!
