Caltrain tunnel #2, just north of Cesar Chavez Blvd in San Francisco, is unique among the four San Francisco tunnels in having two bores, only one of which contains trackage. In my investigations, I haven’t yet learned whether the second bore contained tracks once upon a time, or if it is just one of those vestigial remnants of grand plans that never came to fruition.

The second bore is walled off at both ends, but that doesn’t seem to have prevented certain types of visitors from entering. I wonder what’s in there?
