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.

As indicated in the latest update, I added some LEDs indicating when the turnouts are left thrown on the mainline. After experimenting with some LEDs at home, I’m using a single red LED that is on when the turnouts are thrown:
Eventually I would like to have a little dwarf signal there instead of just a LED protruding from the scenery. I was hoping I could 3D print some at work yet I still don’t have access to the 3D printers due to the lockdown -- there are some dwarf signals available to buy online of course, yet that’s one project where printing my own would be a fun task. I’m not in any hurry and I may be able to access the 3D printers by the time the museum reopens anyway.
Both T151 and T162 have been equipped. Eventually I’ll add one for T150 too. I cannot force the Saturday Operators to pay attention to the signals, yet at least that’s a spot where I can make the layout usage a tiny bit less error prone.
