"The San Diegan"

The Atchison, Topeka & Santa Fe railroad's "San Diegan" at the San Diego train station circa 1945

A more modern locomotive powers the "San Diegan" north to Los Angeles.  This 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.  I know nothing about trains and am guessing this might be around 1955.
