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.

According to OPRRMS on Altamont Press, The black vertically mounted disk shaped object on the top of the cab is, "Receiver for the in-cab hump signals. Used on hump engines at Eugene, LA and Houston until replaced by more a modern radio system. After the RSD15s were retired, they were installed on the three C628s that replaced them, but I don't recall them being on the MP15ACs."

Special Notes

NOTE: If anything is my "life's work" it's my train photos. — If you scan an analog photo of mine, or if you share a digital photo I took that does not have my photo credit, add something like "Photo by Steve Sloan" directly onto the image. It's not enough to say "Photo by Steve Sloan" in the text caption. People download photos off the Internet/Social Media platform and whatever is in the text does not stick to the photo. Then, they get reshared and that data is lost. I deserve credit for my work.

You may not use my photos for profit and/or as part of, or to sell, a product or service without my consent.

Special Thanks!

To all the great folks who helped me out with information for these Web pages!
