Question about the operation of SP's San Francisco Terminal

Steam-era question here.

Does anyone know if SP turned their north-bound trains into the Townsend St. Terminal before entering the station? All the steam-era pictures I've found look like this:

All the locomotives are facing southbound ready to depart. I have never seen an image (yet) of an SP steam strain with the locomotive facing into the station.

If they did turn them, where did they do it? I know there was a wye around the Mission Bay roundhouse, but that seems a little out of the way.

Not really. The terminal switchers would wye the train consists, while the steam locomotives went to the Mission Bay engine terminal and were serviced & turned. They then would back down into the station and couple to their train.

There are a number of books with color photos of the various passenger trains heading directly into the station, both with steam power and in later years with diesels.

Any Espee fans know the answer?
