Coal Hoppers

December 30, 2008

I have two coal hoppers in the works at the moment, both N-scale models and both for my own line of model railways products, ‘Ethan’s Models’. The first is a QR ‘VSA’ hopper, a modern 110T stainless wagon run in the coalfields of central Queensland. The ‘bin’ section of it features lower down the page. The second wagon is a NSW SRA (and now Pacific National) NHFF hopper. This was the first piece of 3D modelling that I undertook, some 6 months ago now, and only just nearing completion! It will be made up of numerous pieces of etched brass, and four blocks of cast polyurethane, generated from rapid prototyped masters.

Two little wagons…

I sat down and drew up a wagon body to suit the Aust-N-Rail NSWGR ‘K’ truck chassis some time ago – the I/IA wagon, a smaller, all-steel counterpart to the Victorian ‘GY’ (incidentally, this uses the same chassis moulding as the ‘K’ and VR ‘B’ van, with an extra few parts applied). These Aust-N-Rail chassis have proven to be a wonderful contribution to the Australian model railway industry – high precision, excellent running qualities and fine detail.

The ‘success’ of this item has led to an even more widespread and popular item, a bodyshell and small components to produce most of the variations on the VR ‘GH’ grain hopper. The prototype was a tedious rebuild of old GY open wagons, with two different styles of top filler hatches and two styles of dump doors underneath, along with miscellanous differing details of ladders and handrails.

Each wagon has had around 12 hours’ drafting applied.

This wagon was commissioned by SAR N-scale Detailers to accompany their range of vehicles for the enormous SCT trip-trains across the Nullarbor. This bodyshell will be rapid prototyped, modified slightly to accept a chassis casting, and set in a rubber mould for casting in polyurethane. The defining feature of these wagons is the ‘corrugations’ along the side, which would prove extremely difficult to build in brass or plastic for a traditional model master.

The process of developing up in 3D was surprisingly simple and straightforward, once the misproportioned (but excellently detailed) general arrangement diagram was traced over. The 3D work and rework took as long as the tracing process, all up exactly 10 hours work.

Hello all,
The point and purpose of this page is to show off some of the projects that I have been working on over the last few months. I’ll go into further detail on several of these items in upcoming posts… for now, some happy snaps!
