Royal Gorge 40 was originally built for the International Railways of Central America (IRCA), a United Fruit Co. subsidiary. Baldwin supplied a large number of 36 inch gauge outside frame locomotives for use in Mexico, central, and south America. The early outside frame 2-8-0s were all equipped with Stephenson valve gear, and had the counterweights cast on the driver centers, like inside frame locomotives. The later ones had the large counterweights outside on the cranks.
Baldwin built IRCA Nos. 35 - 44 between 1912 and 1921. All were equipped with 38 inch drivers, 16 x 20 inch cylinders, and weighed 93,400 pounds. As built they had slide valves and Walschaert valve gear. At some point the IRCA rebuilt them with piston valves, resulting in the locomotive you see in RG 40.
A large number of outside frame 2-8-0s were operated by the Nacionales de Mexico, including ones built by Baldwin, ALCO, and Kerr-Stewart (Great Britain).
