Guys...
I have to admit that I was astonsihed what the #19 could do, after it was put in service in Chama. It has four series-wound traction motors, which create tremendous tractive effort at low speed. (Keep in mind that this little locomotive has all its 47 tons on drivers.) (The #19, although similar to a GE 44 ton locomotive, is not identical. It was built-to-order for the US Navy, and has a heavier, articulated frame.)
Having seen with my own eyes, this beast drag two coupled derelict K-36's out of their beds after several years of dormancy, I respect this piece of machinery very much. I was severely criticized when I brought it from Honolulu to Chama, but I've never regretted it, and never will.
