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.
2022-11-13 - An Update on the Walthers Mainline SD70ACeCategory Randall
The saga with the new Walthers Mainline SD70ACe comes to a very satisfactory end: I got the engines back from Walthers. From what I can tell, their support team did exactly what they said they would do, namely change the firmware in the ESU Loksound Essentials decoders. That has totally fixed the running issues. I spent some time this week-end preparing them. They are now ready to be used as replacements for automation.
