St. Louis-San Francisco Railway 1522 is a two-cylinder, simple 4-8-2 Mountain-type steam locomotive built in 1926 by the Baldwin Locomotive Works for the St. Louis-San Francisco Railway. It was retired, and in May 1959 donated to the Museum of Transportation, St. Louis, Missouri, where it is currently on display. It was returned to operational status in the spring of 1988 and operated excursion rail trips until the fall of 2002 when it was placed back into retirement at the museum.
The 1522 was built to handle Frisco's heavier passenger trains through the hilly Ozark regions. Five other examples of Frisco Mountain-type locomotives are preserved today throughout America. Many railfans regard 1522 as the "The Loudest Steam Locomotive in the World" due to its exceptionally loud exhaust blasts, particularly when working hard.
St. Louis-San Francisco 1522 was built in 1926 as part of the third order of Mountain locomotives for the St. Louis-San Francisco Railway. Purchased for $70,000, the locomotive was built to handle heavy passenger and freight services along the Frisco Railway's Eastern and Western Divisions.
Throughout its career, locomotive 1522 along with the other 1500 class locomotives, was found to be well liked by engine crews, dispatchers, and the motive power department. As they were a true general-purpose locomotive, and well suited for use in hotshot freight service, fast passenger service, or even on local runs. After experimenting with diesel locomotives for a decade since the advent of World War II, the Frisco Railway begin to rapidly dieselize by the end of the 1940s and early 1950s. Ultimately all steam operations ended on the Frisco in February 1952.
Preservation and Excursion Career
The 1522 was originally retired about 1951. The locomotive was selected for preservation and donated to the Museum of Transportation of St. Louis, Missouri in May 1959, where it sat on display until September 1985 when the newly formed non-profit organization, The St. Louis Steam Train Association, selected the locomotive for restoration to operational condition. Work was quickly completed and by April 1988, the 1522 entered its second career. It was returned to retirement in late 2002. This locomotive has done a variety of excursions throughout its excursion career.
October 1988: Inaugural run to Decatur, Illinois.
May 1989: Inaugural run to Moberly, Missouri.
June 1990: 1522 pulled a 22-car excursion over Rolla Hill during the 1990 NRHS annual convention and ran a double-header excursion with Union Pacific 844 once the convention was completed.
June 1994: 1522 was one of the locomotives to participate in the 1994 NRHS annual convention in Atlanta, Georgia and did a double-header with Norfolk and Western 611 from Birmingham, Alabama to Atlanta on its way to the convention.
June 2001: 1522 was invited to pull the Burlington Northern Santa Fe annual employee appreciation special which included a historic tour through the state of Texas. The 1522 was also invited to pull several excursions for the 2001 NRHS annual convention held that year in St. Louis.
September 2002: It was announced that the 1522 was to be put back into retirement as the result of increased insurance rates and flue failures. On September 28th and 29th, 2002, 1522 ran farewell excursions, and right afterwards it was put back into retirement.
