Does anyone have any thoughts on how the extend the power drive line to a third truck on Kozo's Heisler? I think I can squeeze in some beveled spur gears in front of the pinion gear and put another shaft across the top of the rear gearbox. Any known pictures from the folks back at Cass?

I was up at Cass working on the Climax restoration. I should be there next month (Feb, 2004). If I can get into the main shop, I'll take a shot or two and try to post them, or e-mail them.

On the "normal" 3 truck Heisler, the line shaft passes
through the middle truck, and the middle truck gets
it's power from a spur gear on the shaft mating with
an identical spur gear that drives the bevel gear. On the
front and rear trucks the shaft that has the pinion is
on an angle. On the middle truck, the shaft driving
the pinion is pretty much horizontal. Needless to say,
the gear box on the middle truck is different then the
other two to accomadate the spur gears.

You Could try contacting the Mt Rainier Scenic Railroad ( www.mrsr.com ). They have a three truck Heisler, Shay, and my favorite, a three truck Climax. They also have another three truck heisler on static display at their depot. Hope they can help! |

Third truck, F. Burrows Esty wrote an article or two on the center truck with the power shaft to the rear truck. It appeared in the November 1987 issue of Live Steam.
It was for his 1 1/2" Kozo Heisler that I now own. Holler if you need a copy of the article. Brian

Update! During spring break I got to Eble, Wa where the Mt Rainer Scenic RR lives and got a look at the static display 3 truck Heisler. The spring bar on the bottom of all the trucks is arched about its full thickness. The upper bolster is arched about half of its thickness. This makes a nice round hole for all the gears and shafts. On the front and rear trucks the shafts are level. Kozo make a "do it the easy way" and used straight parts and then angled the gearboxes above them. There are some serious size gears in those trucks!
