The '''EMD SW1504''' is a {{convert|1,500|hp|kW|0|abbr=on}} [[diesel-electric powertrain|diesel-electric]] [[switcher locomotive]] built by [[General Motors Corporation|General Motors]]' [[Electro-Motive Diesel|Electro-Motive Division]]. The type was sold only to [[Mexico]]'s national railroad, [[Ferrocarriles Nacionales de México]]; 60 examples were built between May and August 1973. With the breakup of NdeM, the locomotives have been passed to the variety of successor railroad operators in Mexico; some have been sold to leasing companies in the USA.
