Nice history! I ride by that powerhouse regularly. There are old train tracks peppered throughout lower Marin that speak to a different kind of place than it is today.
Sorry for veering off topic but by chance do you mean actual rails and not just visible ROWs like the elevated Center Blvd between San Anselmo and Fairfax? If so I’d love to know where so I can go get some photos of them and especially of their steelmarks showing the foundry name, year, and month they were rolled. I’ve explored a lot of it between Sausalito and the Alto Tunnel and never noticed any, but I also wasn’t…
This is the best resource I've seen.
There are also some tracks halfway up Railroad Grade on Tam. When there are heavy rains, railroad ties wash onto the trail pretty regularly, too!
Curious: do you think the Alto tunnel will ever get reopened? :)
