Title: Truck question on the 3 truck Shay
Post by: Lost Lumber RR on July 10, 2007, 01:17:45 PM
I just got a new 3 truck Shay.  The truck on the tender does not pivot.  Is it supposed to?  If it is, how can I correct it?

Thanks

It is not suppose to.  It is fixed.

The drawings and digitalmentation show it pivoting, but they discovered in testing the prototype model it doesn't work like the "real thing".

The coupler is truck-mounted, the drawbar is body mounted.
Try backing a long-ish train, and the term most closely applicable is "jack-knife".

If you were to body mount the coupler, you might be able to get away with the truck pivoting.
But I wouldn't.
Easier to get the thing on the track if you only have to align the water bunker.

Takes 5-10 minutes to make it free-pivoting, but the conversion is permanent if you want the factory locks.
