A 15" gauge 3"=1' or 7.5" gauge
2.5"=1' scale Shay project
|The "Riverview Shay" is a new design large scale live steam
loco. It can be built as a 3" scale standard gauge 80 to 3 truck
Shay based on the Lima Shay CN3199 prototype built in 1928.
It can also be built as a 2.5" scale of the prototype120 ton Lima Shay running on 7.5" gauge track. Some of the truck parts are changed and the wheels are made for the 7.5" gauge frogs. The engine mount is slanted for the narrow gauge just as the Lima Shays were on narrow gauge as can be seen at the right. CN3199 is a 3' gauge.
The prototype 80 and 120 ton work out well when done in scale 3" and 2.5" ending up the same size.

3D CAD drawing of the "Riverview Shay"
The CAD drawing is intended to be a sample of the over 30 "D"
size pages to come. It is not intended to be totally readable on
the web site. A complete set of drawings should be ready lete
this summer as the engine is built.
