WW Wheat Wagon (Standard Gauge, HO Scale)

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, has also been produced.  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.
