Prototype Information
The Schafer Brothers Logging Company had a Class A 15-2 Shay locomotive . The Olympic Peninsula Logging Company is imagineered over one of the Schaefer Brothers Logging Company's line. The alternate history is that the OLPC inherited rolling stock from the US Army's Spruce Division line's contractors, many dating from around 1890 or earlier. One of those inherited items could have been a Class A Shay.

The WWSL
One of the WWSL's future modeling projects is the modeling of representative locomotives of the Class 1 and Class 3 railroads operating in the Montesano, Wa. area. It would be stored on a display shelf and maybe posed on the WWSL for a vignette photograph.
I liked the idea of building a Class A for for two reasons: 1)
the 'boot' boiler, and 2) a scratchbuilt locomotive is a requirement for
the Master Model Railroader Achievement Program.
The Shay locomotive was a patented design built by the Lima
Locomotive & Machine Company of Lima, Ohio. Strange looking and lopsided to the uninitiated eye, Shay
locomotives proved to be very effective on logging railroads in particular and some 2770 were
built between 1879 and 1945 (Koch 1971).
Modeling Information
There are no Class A Shay locomotive models in HO scale.Bachman has a three Cylinder Assembly and miscellaneous ancilliary parts available for purchase on their parts web site. The fact that my shay would be a non-powered model lends to an idea of purchasing Cylinders, scratchbuild the locomotive frame and tenders, and kitbatch the running gear.
Wiseman Model Services
has the MDC Roundhouse HO/HOn3 scale 2 Truck and 3 Truck Shay
Locomotives kits and detail parts. Some of those detail parts may be appropriate for this locomotive.
Engineering
The boiler, cab, and tender were carried on two center-bearing swivel trucks. The boiler was offset to the left of the locomotive center line to
balance the weight of the engine. The engine had two cylinders, on the right
side. Power was transmitted from the crankshaft to the two trucks
via a longitudinal shaft system running low on the right side of the locomotive. Universals and
slip joints accommodated curves and uneven track. Bevel gears transmitted power from the
shafting to the drive wheels.

I am going to
'super-detail' it but that effort is going to be later than sooner. I
have in my railroad library several books/phamplets on the
Shay locomotive that I will use for that project. I will update this page
when the project is completed.
