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 looking very hard :)
Neat, I’ll have to go check that out again. As for the tunnel I’m not really plugged into the local politics enough to have an informed guess. From what I’ve read SMART seems to be widely hated by these same groups of extreme-anti-growth people, and the other tunnel whose name I forget has already set the precedent of SMART sharing the tunnel with a walking/bike trail. That makes me lean toward “probably not” since it could incentivize southward SMART expansion from the current Larkspur terminus :/
e: I also want to go look for any remnants of the White Hill / Bothin Tunnel if it isn’t on a parcel owned by someone who would mind. There is a trail right there that goes down to the parking area at the SFD Blvd bridge, but the actual portal remains (if there are any) might be on the Girl Scout Camp’s land. Unsure.
