I’m having a heck of a time figuring out just WHAT this is: obviously ALCO (or maybe MLW), little stack (so non-turboed), looks kinda like a S-1 or S-3, but it appears to have radiator on NOSE as well as sides…
Anyone have any ideas? (BTW, it hangs around here in Cayce, SC at the steel mill, along with a NW-2, and two others I haven’t identified yet).
…I know nothing about this specific engine, but believe the openings near the front {Radiator}, on each side would simply be exhaust openings for the warm air flowing thru the radiator.
A little internet sleuthing has determined that the locomotive is a rebuilt Alco S-2. One of the spotting features for them was a square front radiator section–you can see the rebuilders covered up the rear portion of the opening in the last view–giving it the appearance of an S-1 or S-3, when it wasn’t.
These types of rebuilt Alcos were done by Johnson Rail Services of Cornelia, GA. This loco was seen at their facility in October of 2002 from a report by Mark Sublette. Here’s a link to that (it is down about 2/3rds of the way on this page.)
The engine itself probably has a Catepillar diesel engine of some kind (hence the 425 horsepower rating). Quite a few industrials have these rebuilt by Johnson Rail Services, and they all look about the same.
The article goes on to state that it was previously Laurinburg & Southern S-2 #132.
