WW Wheat Wagon (Standard Gauge, HO Scale)

Photo of test model.
The WAGR/Westrail WW standard gauge wheat wagon entered service in 1966 and formed the mainstay of the standard gauge grain fleet for over 45 years until Cooperative Bulk Handling introduced their own locomotives and rollingstock in 2012.  They were affectionately known as "Willie Weeties".  

The Marbelup Models WW consists of a 1-piece 3D-printed body and an etched brass roofwalk which incorporate the ladders and handrails as a "fold-up" assembly (no soldering required).  Additional etched brass parts are also included for the corner steps and brake wheel.

For prototype information, please refer to the WA Wagon Pages.

The later version with air-operated roof hatch and no roofwalks, i.e. the AGWY and AGSY, is also available.  The difference between the prototype AGWY and AGSY relates to improved seals on the discharge hatches (AGSY) to allow use with canola, which is finer than other grains.  The model can represent either version.  Some WW's also had the improved seals fitted and were coded WWS.

The AGWY/AGSY has an extra air cylinder on the end opposite the brake wheel, in connection with the air-operated roof hatch.

Both the WW and AGWY/AGSY are available to order now. 

Expected selling prices for the body-only "kit" (including etched parts and Kadee #262 coupler boxes) are $80 for WW and $80 for AGWY plus postage if required.  (Prices are subject to variation due to changes in the Euro exchange rate.)

The purchaser must separately obtain parts to complete the model including bogies, couplers, brass wire, paint and decals.  Suitable bogies are available from Kadee (#569 or #1569).  Detailed instructions including list of parts required are now available online.  

Marbelup Models has ordered some suitable bogies and these will be available, together with couplers, air hoses, brass wire and fixing screws, as a "parts kit", containing all the extra parts necessary to produce a running model.  Quantities are limited.  Glue, paint and decals not included.  Two types of "parts kit" will be available:

"Premium Parts Kit" including Kadee #569 bogies, and parts as listed above: $25 per wagon.
"Quality Parts Kit" including Tichy #3009 bogies, Intermountain metal wheelsets, and parts listed above: $15 per wagon.

The Kadee bogies are from HGC plastic, and are a 2-piece design which provides compensation over uneven track.  They are are also self-centering, an aid to placing wagons on the track.  Kadee wheelsets have black metal wheels on a plastic (Delrin) axles.

The Tichy bogies are 1-piece moulded in plastic.  Intermountain wheelsets have brass wheels and axles, with a weathered finish.
