This is a Lightwave modeling project which may or may not end up as a 3D print. It is based on blueprints, a Lima model loco of a similar Australian National Railways GM class loco, and many photos sourced from the internet (particularly the VR Homepage) and photos taken by me at an open day at the Seymour Railway Heritage Centre. The model is of the S303, a former Victorian Railways loco, now owned by the SRHC.

S303 in Victorian Railways livery at SRHC open day, Seymour, Victoria, 17 Oct 2015. At some stage, the original bogies were replaced by ‘flexicoil’ bogies. As I had already modeled flexicoil bogies for the X-31 loco model, I could use them for this project, along with some other X-Class components such as hoses and horns.
Another great reference source was from the DVD series ‘Railroad Australia’, which among other stories, featured a ‘Streamliner’ loco, the B61′ showing lots of driver cab interior shots which were similar enough for the S-class modeling. The series also featured the 2016 Streamliner convention at Goulburn NSW, showcasing a collection of restored and working B, S, GM and other ‘bulldog’ nosed streamliner locos. This was particularly helpful to see details of typical S-Class roof layouts including fan placement.
4-way view of my HO scale ANR GM 32 loco. The S-Class was the Victorian Railways version of the Commonwealth Railways (later Australian National Railways) GM locos. I was going to use this photo as the basis for the Lightwave model, but decided instead to use the clearer line drawing blueprints I found on the web.
Lightwave 4-way view set up with the line drawing blueprints. The top-left corner blueprint is a bit difficult to see in this screengrab, but is from a double-ended B-Class loco driver’s operation manual, as I was not able to find an S-class top view blueprint. The driver’s cabs of the B and S-class locos are similar.
Various stages of modeling in Lightwave. Modeling the ‘bulldog’ nose and front windows was quite a challenge!
On the B and S-Class locos, the side wall framework is partially visible through the grills, hence the need to construct it in the model.

Rear details and roof fans added. The S-class loco has a second cab with driving controls at the rear on the right side, for drivers known as ‘hostlers’ to perform short haul duties and moving the locos around yards. The hostlers cab also houses the battery boxes.
Lightwave is a 2-part program: Modeler and Layout. These renders are from Layout.
Rear, with hoses still to be added. No surface textures added at this stage.
Front, Lightwave 11 Layout. There seems to be a render problem in Lightwave 11 around the nose section at the bottom of the front windows. The render problem is not present using a demo of Lightwave 2020 (see below).
Lightwave 2020 render. The checkerboard ‘watermark’ is because I was using the demo version. Note that 2020 demo has rendered the nose section properly.
