The '''Southern Pacific Class GS-7''' is a class of seven [[4-8-4|4-8-4 "Northern"]] type [[Steam locomotive|steam locomotives]] built by the [[Baldwin Locomotive Works]] for the [[St. Louis Southwestern Railway|St. Louis Southwestern Railway (also known as the "Cotton Belt Route")]], as Cotton Belt Class L1 [[Steam locomotive|steam locomotives]] but would be later leased to the [[Southern Pacific Transportation Company]] where they would be classified as GS-7.<ref name=":0">{{Harvp|Strapac|1999|p=140}}</ref><ref name=":1">{{Cite book |last=Dunscomb. |first=Guy L. |url=https://www.google.com.au/books/edition/A_Century_of_Southern_Pacific_Steam_Loco/iO9SAAAAMAAJ?hl=en&gbpv=1&bsq=A%20Century%20of%20SP%20Steam%20Locomotives |title=A Century of Southern Pacific Steam Locomotives, 1862-1962 |publisher=Guy L.

== History ==
During the [[World War II|second World War]], the [[Southern Pacific Transportation Company]] needed more motive power to tackle the issues throughout the [[World War II|second World War]], the [[St. Louis Southwestern Railway|St. Louis Southwestern Railway (also known as the "Cotton Belt Route")]] decided to make an agreement with the [[Southern Pacific Transportation Company]] to lease seven of their own Class L1 [[4-8-4]] locomotives to the [[Southern Pacific Transportation Company]], this resulted in what would become the Southern Pacific Class GS-7.<ref name=":0" /><ref name=":1" />

The Southern Pacific class GS-7 actually was one of two classes of ex-Cotton Belt Route Class L1 that were leased to the [[Southern Pacific Transportation Company]], with the other one being the [[Southern Pacific class GS-8|GS-8]].<ref name=":2">{{Cite book |last=Garratt |first=Colin |title=Illustrated Book of Steam and Rail - The History and Development of the Train and an Evocative Guide to the World's Great Train Journeys |last2=Wade-Matthews |first2=Max |publisher=[[Barnes & Noble Books]] |year=2003 |isbn=9780760749524 |pages=87}}</ref>

The Southern Pacific class GS-7 and GS-8 locomotives were built at the exact same time that their [[Southern Pacific class GS-1|GS-1 locomotives]] were built.<ref name=":2" />
