The file 'G-scale F7, Motorised 3D Printer Model' is (stl) file type, size is 306.7KB.
This is one of several "things" that I have been working on for a Super Chief style train in G-scale. (not 100% accurate, but close enough)
I will run off battery with radio control. If you want pickup from the track, you will have to figure that out yourself, sorry.
It could probably be down-scaled (everything) to run on 32mm track (don't know about the bearings?), but for HO I suspect that you would need to look at a different mechanism.
Inspiration from https://www.thingiverse.com/thing:4796985
I used the front end for the profile, did a bit of resizing and remixing to it, also used the chassis, with modifications and fixes.
All other files have been re-drawn completely,
Then I did a mech design based on the mech from https://www.thingiverse.com/thing:3097453
I will upload the different parts in a series of "things" listed below
