Nostalgia & History > SP SDP45s in Tracy, in 1974

On Sunday morning, November 10, 1974 Southern Pacific SDP45s 3204, 3206 and 3208 lead the RVOAZ in Tracy Yard. The steel block is a setout for Pittsburg. (Thanks WAF for this information.)

These were later reclassified to freight service and reclassified in June 1985 to SP Class EF636-13. This locomotive was retired in November 1990, sold 1991 and scrapped.

Most of the SDP45 got M5 horns, many from the retired FM H-24-66 locomotives. 3208 was one of the first to have it's standard Nathan P3
horn replaced by an M5 as pictured.

Great stuff! More old SP diesel photos, please!

Good looking photos of handsome diesel power. Thanks for sharing.

Sad that one of the SP SDP45's could not have been saved and preserved. I guess you can't save them all, but it's still too bad that one didn't get saved. Thanks for sharing these great images.
