train tunnel

The Sunset Tunnel, known as the Duboce Tunnel (San Francisco).­

There is not enough clearance between the train and the tunnel walls, so you *must* hide in a small alcove when you see a train coming.­ The light at the end of the tunnel on this photo is actually a muni train coming.­

No trespassing! This is REALLY a DANGEROUS place!
