Notes

¹ Many sources list 458 as becoming NdeM 400 and 2250. However, 2250 has outward-sloping valves like 459, not an inward-sloping cylinder casting like 458. Thus, either conventional roster wisdom is wrong, or the Mexicans did a whole lot more work in the conversion process than anybody knew. If anybody has a picture of 401/2251 in service, I'd appreciate seeing it to verify this conclusion.

² The K-27s were built as saturated steam Vauclain compound engines, but were converted to conventional single expansion locomotives early on. During this conversion, the units were converted to slide valves - some inboard, some outboard. Later in their lifecycle, 452-456, 458, 459, 461, 463 and 464 were given superheaters, piston valves, and Walschaerts valve gear. Engines 450, 451, 457, 460, and 462 were never retrofitted with superheaters, though 462 was eventually given piston valves. The ones with inboard valves received Stephenson valve gear initially and were later retrofitted to Walschaerts. Later, 464 was converted back to saturated steam while on the Huckleberry RR in Michigan.
