Woolshed Flat Final Video
Built for OcTRAINber 2020, ‘Woolshed Fat’ is a pizza-box style circular diorama using R24 narrow gauge Lego track. The diorama itself sits on another circle of R24 track and, powered by two technic motors, the entire diorama rotates. In fact, the entire weight of the diorama sits on 8 train wheels.
The scene is based on the Pichi Richi Railway in the Flinders Rangers, South Australia. Now preserved as a tourist railway, the line was once part of the South Australian Railways (SAR) narrow gauge network (built to 3'6" gauge). These lines were built as a cheaper alternative to SAR’s main gauge of 5'3" (the same as neighbouring Victoria).
The locomotive is the ‘Coffee Pot’ Steam Motor, built for the SAR in 1905 by Kitson, Leeds (loco) and Britannia Carriage Works, Birmingham (carriage). It was preserved, and now operates on the Pichi Richi Railway, its original home.
Due to the tight radius curves, the Lego version was built to the relatively small scale (for Lego) of 1:55. This scale reduces overhang while leaving enough room for a Technic motor and 4xAAA batteries. The rear bogie is powered. The model uses 3D-printed wheels, cranks and rods, but is otherwise a ‘legal’ build. Unlike the prototype, the front wheels are pivoted to allow for the tight curves.
