Coal Car Test Truck

I refined the truck design a little over the holidays, and assembled a couple of test prints. The mechanical aspects are fairly good now, and as you can see it equalizes quite nicely. I just have to improve the supports a little so I don’t lose any more brake beams!

Coal Car Trucks

I’m taking a little break from Percy as I wait for some slightly larger, more powerful motors that I ordered earlier this week. I cast about for another project to pick up for a week or two and alighted on the coal cars. They’ve been waiting for a resolution to the weight problem, and they […]

Coal Car Test Print

From 3D file to the first print always makes me feel like a ten-year-old on Christmas morning. A ten-year-old with a ventilator, gloves and safety glasses in a basement workshop that smells more of chemicals than of pine. With this being the first whole car I’ve attempted to print, I hardly expected it to work […]

Coal Car Brakes

The brake systems on hopper cars are often tight for space. So, it’s useful to be able to check clearances before construction. In the case of the coal cars, I found the train line was a little too close to truck bolster for my liking, and so, I raised it a scale inch or two. […]

Standard Parts

As I’m working on a 3D model of a freight car, there are some parts that lend themselves to reuse. Brakes, stake pockets and pipe fittings are natural candidates for standardization. So, I’ve established an OnShape document of some standard parts that I can import and use on any other car I might design. John […]

Coal Car Progress

For one reason or another, I’ve been absent from the railroad room quite a bit these past few months. This makes progress on physical projects difficult, but virtual projects can continue. The coal car, which I’m almost ashamed to say has been on my desktop for a year, is nearing completion. In thirty years of […]

Modelling on the Road

Years ago, I worked as a consultant for a database company. A road warrior, often away early Monday morning, returning home Friday evening. It seems like other modellers are able to get some modelling done while travelling; I’ve even heard of a pilot who would build models in the cockpit during long flights. However, the […]
