Indeed, those tracks are for what we always called "streetcars." Had to be careful of the groove. Schwinn bike tires could drop in and jam up. I had a Murray Ohio which had fatter tires. Still, steer clear of the groove.

I remember in the 50s that there were men in their large coveralls who lubricated the curved tracks. The only sand dunes left were at the future site of St. Ignatius High School in the outer Sunset District. My parents' house, southeast of this shot, had just been built in 1924. Framed in solid redwood, rough cut. Lath and plaster walls. Lovely homes for working class families.

The girder rail and close spacing of the two tracks are dead giveaways.

That does not look like normal railroad track. Any idea as to what is going on?

[Streetcar tracks, possibly for the N Judah Line, which opened in 1928. It ends at Ocean Beach. -tterrace]
