That is an ALCO MRS-1 one of eighty three adjustable gauge units built during the Korean War for the U.S. Army, #s 2041-2123. Most likely it did run at the ammo plant.
Here are two pictures of MRS-1 engines at the Bluegrass Railroad museum I took and the sign explaining them.
Werethere some built in WWII for service in the Middle East and USSR?

I think this is the engine I would see when it was running. Anyone know the history of it? What does the SRYC mean. It seems to me it ran at the ammo depot in California. Don
Sierra Railway Company of California IIRC.
The ALCO RSD1 8669 at the Tennessee Valley Railroad Museum, located in Chattanooga, TN, was built in 1942 for use on the Trans-Iranian Railway to ferry supplies into Russia during WW II. The 8669 has six wheel trucks and a tapered cab side, with a beaded board ceiling in the cab. I had the opportunity to routine-service and run this engine for one week during the summer of 1984, while my regular engine, Ex. SR 722, was undergoing its monthly boiler wash. The 8669 was a smooth running loco, and gave me a break from firing for one week. Having a similar brakestand to the one in 722 made for an easy transition to operation. NOTE: Photo is 8677.

I hope you didn't have to adjust the brake rigging on those trucks.
Fortunately, never had the "pleasure"! Most of my shop hours were consumed with the steam engines.
"Baby Trainmasters" were FM H-16-66s built after the introduction of the H-24-66 "Trainmaster" engines in 1953. The differences were primarily inside the engines. For easier construction, the H-16-66s built in 1953 or later used the same body parts, trucks, etc. as the Trainmaster, so externally were almost indistinguishable except for being about 3-1/2' shorter than the H-24-66.
