The State Belt roundhouse in early 1965: Note that there is no turntable. Although the tracks have been gone for many years, the structure still exists today (2003) as a somewhat bizarre office building. That's Alco S-2 #24 peaking around the side, and across the Embarcadero to its left stands the waterfront piers that it served.
Alco S-2 #25 switches the Freedom Train on December 13, 1975.
