The photo is at the end of track on 4th St. at the Southern Pacific Santa Ana Station. Note the hood over the headlight.
The photo is unusual that there are not many views Red Cars at the Santa Ana SP Station. According to Interurbans Special 21, during World War II, alternate outbound trips from Los Angeles would continue east past the PE Santa Ana Station at 4th St. and Mortimer to the SP Station. Out of view behind the 4508 and the billboards was a small three-track yard for car storage. This trackage back to the PE Santa Ana Station and the storage yard was abandoned immediately after World War II ended.
