Interesting idea. If you follow up on this, please post a "how-to" with photos.

A few weeks ago my friend Thom shared with me some trains made by Sarissa Precision for 28mm wargaming. 28mm is generally considered 1/56 scale.
These models have a most alluring charm to them. They look "narrowgaugy", and even a bit of steampunk.
If my math is right, using On30 track (same gauge as HO), works out to pretty close to 24" gauge in 1/56 scale.
Edit: My math was wrong... it will be 3 foot gauge... Thank you Dan. The thread title was corrected. -Kevin
So, I could motorize a locomotive with an HO scale mechanism and use On30 trucks and trackage to make a reasonable 2 foot gauge railroad. There is nearly anything you can image for building materials in 28mm scale.
I am obsessed with this idea. I love the look of these trains. They deserve to become mechanized and put into service.
There is too much possibility here for a railroad with personality.

Living the dream.
