1890-something 4-6-0 "Odyssey" Steam Locomotive

The "1890-something" system is a solution to a problem I've had for quite some time. I want to display small-scale trains, but don't have the space or budget to run a conventional model train set. But, what if there was a system that prioritized ease of production and durability? So, this is what I came up with, and I've been working on this for the past few weeks.

First off, I am not prioritizing historical accuracy or fidelity by any means. I'll include engines from the 1910's or 1880's (despite what the name suggests) and mix rolling stock from different locations. However, I'm aiming for a broadly "wild west" theme. The models have no defined scale, though I accidentally made them kind of similar to HO scale. I designed some rudimentary tracks for displaying the models, though I'll admit they're a little finicky.

At their core, these models are meant to be static displays, cheap and easy to produce with no additional parts.

This was the first locomotive I designed some time ago, and it shows. However, it's still pretty good, though the design is from a 1910's locomotive. The roof and cab are separate parts for structural reasons, but it also helps to add more color variation if those are printed in different colors. I printed the smokebox using my printer's AMS system to add a bit more detail, but it can be printed in a solid color.

INSTRUCTIONS

All parts have already been aligned for ease of printing, but an image of the CAD model should provide good reference for assembly. Below are the instructions. Super glue is recommended for most parts.

• Attach the piston rods to the sides of the boiler section (I recommend using modeling cement on this part to avoid fogging)

• Put the roof on the cab, and them mount the assembly to the back of the locomotive

• Attach the front of the locomotive to the boiler, making sure to line up all the pegs

• Attach the couplers on either side, making sure they're oriented correctly (reference image for correct position)
