Southern Pacific 1673
Southern Pacific 1673, Steam locomotive at Southern Arizona Transportation Museum, Tucson, United States.
Southern Pacific 1673, a Mogul type locomotive with a 2-6-0 wheel configuration, represents early 20th-century railroad engineering at the museum's entrance.
Built in November 1900 by Schenectady Locomotive Works, this locomotive traveled over one million miles hauling freight between Tucson, Nogales, and Yuma until 1955.
The locomotive appeared in the 1955 film Oklahoma before Southern Pacific donated it to Tucson, marking the transition from operational use to historical preservation.
Visitors can examine the restored locomotive daily from outside the museum at 414 North Toole Avenue, while guided tours provide detailed information.
The engine underwent conversion from coal to oil fuel in 1906 and received a superheater installation during its 1922 rebuilding at Sacramento shops.
