Santa Fe No. 5000 is a 2-10-4 "Texas" type steam locomotive constructed by Baldwin Locomotive Works in 1930 for the Atchison, Topeka and Santa Fe Railway. No. 5000 was immediately nicknamed the "Madame Queen" and remained a unique member of its own class. It was donated to the City of Amarillo, Texas in 1957 and is currently maintained by the Railroad Artifact Preservation Society. Santa Fe 5000 is on the National Register of Historic Places.
