Scale Train Drawings

Title Image

Welcome to the Trainiax drawings page! This is a collection of drawings that I have been working on since late 2000.



With a couple more RSD-12 drawings, I've reached my goal of 250 drawings for 2023. I'm hoping to continue adding more ALCO drawings in the remainder of the year.


In one of the more noteworthy omissions from the drawings, in 23 years I have never drawn a 6-axle ALCO RSD-series locomotive in any scale. That changed today with the arrival of the RSD-12 in 1:18.

The first step started a week ago with the making of ALCO Tri-mount trucks. This was time-consuming but straightforward as I had several excellent ALCO mechanical diagrams to work from. The second step was to stretch the frame and hood on an existing RS-11 drawing - also straightforward since most of the other dimensions are the same.

The third step involved searching and sifting through hundreds of RSD-12 and RSD-15 photos to try to decipher the finer underframe details - which was the most time-consuming part. Unlike for previous ALCO models I've drawn, I don't have my own photos or direct measurements of an RSD-12.

About the Drawings


My drawings would not be possible without the extensive contributions from many site viewers sharing photos, diagrams, phase details or corrections, and I am very belatedly publicly sharing my gratitude to those who have helped. (If you've sent me stuff and you're not on the list, please remind me!)

A special thank-you to
