None of those had a photo of the tunnel entrance… why is there a rail tunnel that’s easily accessible to cars? Here in DC, the Metro is completely segregated from auto traffic. Is the SF rail running on streets?
Oh, well I can totally see how a car would end up there if it was dark, stormy, or the driver was drunk/high. We gets cars on the local bike path all the time - usually a drunkard, but sometimes just somebody who thought it was a driveway.
The SF MUNI system has light rail vehicles which do sometimes run on surface streets, similar to a trolley.
