Santa Fe's PA-1 #59L, the locomotive above, was among the rarest early-generation diesel locomotives in the United States. When it appeared that #59L was headed for an uncertain fate, the Museum of the American Railroad expressed interest in acquiring and restoring it. Thanks to the Smithsonian Institution and  the BNSF Railway, the locomotive was donated and moved to the museum’s new home in Frisco, TX in May 2011. 

Santa Fe F7 #43-C is ready to depart San Diego for Los Angeles on April 7, 1968 with
a section of the San Diegan   (Posted on Facebook April 27, 2024 by Robert Slavey)

This locomotive has the same number -- 43-C -- as the one in the photo above.  Maybe this photo was taken on the same day as the photo above, or maybe all the northbound Santa Fe locomotives bore this number.  This photo appears to look west from where the train tracks head inland below today's La Jolla Colony.  To the left is Rose Canyon, where the I-5 freeway is.
