The [Milwaukee Road](/source/Chicago%2C_Milwaukee%2C_St._Paul_and_Pacific_Railroad) was the first railroad to take delivery of the RSC-2, initially assigning them to their Valley Division (headquartered near [Wausau, Wisconsin](/source/Wausau%2C_Wisconsin)) in November 1946. This was done in order to study the effects of an all-diesel roster (i.e. no steam locomotives available as a backup). The experiment was deemed a success and soon all steam locomotives were gone from the Valley Division. RSC-2s would faithfully serve the Milwaukee Road for many years, until being replaced in turn by the [EMD SDL39](/source/EMD_SDL39). ALCO also exported these units to the state railway of [Portugal](/source/Portugal), where [Portuguese Railways](/source/Comboios_de_Portugal) (CP) designated them [Série 1500](/source/CP_Class_1500). These locomotives were built for the [Iberian track gauge](/source/Iberian_gauge) of ({{Track gauge|1668mm}}). The last units in Portugal served in regular passenger service into the first decade of the 21st century. Of these, five are still running today, 70 years after their arrival (one is a museum locomotive, while the other four are owned by track maintenance companies). Five units were exported to the [Algerian National Railways](/source/Algerian_National_Railways) where they were used in passenger train service. ==Original buyers== {| class="wikitable" !
