These are from the U.S. President's Railroad Commission Photographs held at Cornell University.

I highly recommend perusing the entire San Francisco collection of 41 images here:

Another view of Quint Street looking the other way, maybe from another location on the street:


This is a view of the ATSF-SP Illinois Street tracks crossing the WP's yard lead at 25th Street. Train is headed toward Mission Bay yard.


Consumer's Rock and Cement--not sure where this was.

7th Street curve at King St. train is probably heading out the old mainline on Townsend Street:
