Southern Pacific's Geeps and Cadillacs - Vintage Workhorses

Enjoy the sights and sound of forty year old GP9, SD7 and SD9 diesel locomotives moving freight over Southern California mainlines and branches in the 1990s. Nicknamed "Geeps" and "Cadillacs", these locomotives revolutionized American railroading when they were introduced in the 1950s. Their popularity was due to their efficiency, ease of maintenance, and operational flexibility. You'll see why SP was still relying on these venerable workhorses in the 1990s when they were captured on film for your enjoyment.
