The Randall Museum in San Francisco hosts a large HO-scale 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 Museum Model Railroad and I maintain a separate tech blog for all my electronics & software not directly related to Randall.
