I built this custom, 1/24th scale railbus from scratch, using a few parts from an old Hubley 1/20th scale Model T Depot Hack kit. I’m also using the battery and electronics from a Team Losi Micro-T r/c car set. Losi cars and components can be purchased from their website, as well as Amazon and other online sources, and many hobby shops.

The rear wheels unit, including the differential and universal joint, is from a Bachmann large scale RGS railcar. The front wheels are from a Bachmann “gandy dancer” handcar. (I’ve been told that these are the same wheels used on the pilot truck of the Bachmann 4-6-0.) All these parts were purchased from Bachmann’s online store.

The motor is a 6 vdc motor with a 115:1 gearhead. I got it from Pololu.com

On October 26, 2012 I posted a video to YouTube, showing the first test run of the railbus chassis under construction. I wanted to make sure everything worked before getting too far into the build. It runs very smoothly and quietly. Top speed isn't very fast but is acceptable, and it's probably pretty accurate for a heavily-loaded Model T.

As of November 18, 2012, the railbus itself is finished. All that remains is to make the driver, passengers, and some luggage. When I’ve done that I will shoot a new video of the railbus in action.
