On Friday June 27, 2025, my son Kenneth's HO models of Southern Pacific (SP) 4357 and a GS-4 double heading passed my model of SP 3509 at the Tri-City Society of Model Engineers model railroad in the historic Niles depot in Fremont, CA. This SP 4357 is an Athearn Genesis model, the GS-4 and SP 3509 are BLI models.
The real 4357 was an SP MT-4, 4-8-2. Reportedly it was built in the SP's Sacramento Shops in 1927, retired in 1957 and scrapped in 1958.

Click Photo To Enlarge

Southern Pacific (SP) "alligator" 3101 was in the Eugene, Oregon power pool on Friday, June 21, 1974.
SP 3101 was an ALCo RSD15, DL600B, SP Class AS624-1. Reportedly, it was built in 1959, construction number 83484, as SP 4817 class DF-502. It was leased in 1960 to T&NO as 251. It became SP 5161 in the 1965 renumbering as class AF624-1. In 1972 it was reclassified to switcher Class AS624-1 and then renumbered SP 3101. It was retired and sold in 1978.
According to OPRRMS years ago on Altamont Press, The vertically mounted disk shaped object on the top of the cab is a, "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."
