A long long time ago these photos were posted here. But, the server I had then was shut down, so the links I had then were broken. Plus, I have added a lot more information. So, I hope resharing is okay.



SP 3100 "even", ALCo RSD15 DL600B on the Eugene hump. Eugene, Oregon Jun 21, 1974.

Reportedly (sources) SP SP 3100 was built in September 1959, ALCo construction number 83483, as SP 4816 class DF-502. Leased in March 1960 to T&NO as 250. These were the last units added to the T&NO roster before the 1961 merger. Became SP 5160 in the 1965 renumbering as class AF624-1. In April 1972 reclassified to switcher Class AS624-1 and renumbered SP 3100. Retired and sold May 1978.



Oregon and Washington was a favorite destination as soon as I was old enough to drive long distances.



In the early 70's it was very interesting with ALCos, Baldwins and Cadillacs on the SP and many pre-BN painted units and ALCos on the BN. The SP gators were a favorite!
