About the Model Railroad

RTAC Software


The Randall Museum in San Francisco hosts a large HO-scale model model railroad. Created by the Golden Gate Model Railroad Club starting in 1961, the layout was donated to the Museum in 2015. Since then I have started automatizing trains running on the layout. I am also the model railroad maintainer. This blog describes various updates on the Randall project and I maintain a separate blog for all my electronics not directly related to Randall.

2022-08-28 - Updates to RTAC and Conductor 2

Category Randall

I’ve spent the last couple months mostly working on a new version of my automation software: Conductor 2. The new version has an entire new scripting language, advanced logic for block handling, and a simulator.

It’s almost ready for trial at the museum. For now, it works neatly using the simulator:

I have detailed updates about Conductor 2 on the technical blog here.

I also have updated RTAC, the Android software that runs on the tablets at Randall. These are mostly little implementation technical details, and not directly visible to the visitors. The latest version of RTAC is now available on the Google Play store.
