Santa Fe was the biggest customer for the 75 locomotives of this class produced by ALCO between 1956 and 1960, buying 50 of them. The RSD-15 could be ordered with either a high or low short hood; railfans dubbed the low short hood version "Alligators"; all the Santa Fe units were this version. Six survive, two operational, in railway museums. (Santa Fe pics 1,2, Broadway 3)
