Atchison, Topeka & Santa Fe
3751 is a class 3751 4-8-4 steam locomotive built in 1927 by the
Baldwin Locomotive Works in Eddystone (Philadelphia), Pennsylvania for
the Atchison, Topeka & Santa Fe Railway (ATSF). 3751 was the first
4-8-4 steam locomotive built for the Santa Fe and was referenced in
documentation as type: "Heavy Mountain", "New Mountain", or "Mountain
4-wheel trailer". No. 3751 served in passenger duties until being
retired in 1953.
The locomotive was then placed on display in San Bernardino until it
was restored to operating condition in 1991. It is currently located in
the Central City East neighborhood of Los Angeles and has been listed
on the National Register of Historic Places since 2000. It holds the
distinction of being the oldest surviving 4-8-4 type steam locomotive
in the world.
The locomotive is currently owned and operated by the San Bernardino
Railroad Historical Society, which uses the locomotive to haul
occasional mainline excursion trains. However, a federally mandated
15-year inspection put it out of service for three to four years. No.
3751's overhaul was completed in September 2022.
