Baldwin Locomotive Works built this 2-10-2 for $30,753 in 1916. It is a good example of a "drag freight" locomotive, able to haul heavy but slow trains. It has 60' drivers, 20' by 32' cylinders, a boiler pressure of 200 lbs., and weighed 601,610 lbs.

One of only eight Santa Fe type to survive the scrapper's torch, Duluth, Missabe & Northern (Iron Mountain) No 502 was saved and is now at our museum. The Santa Fe type was one of the dominant steam locomotive wheel arrangements of the 20th century. Between 1903, when the Atchison, Topeka & Santa Fe commissioned the first ones, and 1931 when the Reading Company received the last examples, some 2,200 of the heavy freight engines were built for North American services. That's twice the number of 4-8-4 Northerns and three-and-an-half times the total for the 2-8-4 Berkshires that was constructed.

Now an improbable 2-10-2 revival was the result of Chinese imports returning the wheel arrangement to the active list. Two engines – Nos. 6988 (built 1995) and 7081 (1986) - arrived at RDC's Iowa Interstate Railroad in late June, 2006, broke in on IAIS freights, the units made their public debut on a series of excursions out of Rock Island, Ill. on  September 14-17.
