Southern Pacific No. 7457 is an EMD SD45 diesel locomotive built by the Electro-Motive Division for the Southern Pacific Railroad in 1966.

History[]

Southern Pacific No. 7457 was manufactured in 1966 and was delivered to the Southern Pacific Railroad that same year in 1966. When it was first built, it was actually first numbered as 8800 and given the classification of EF636-1.

It weighed in at an impressive 368,000 pounds (167,000 kg), was capable of reaching a top speed of 65 mph (105 km/h), had a power output of 3,600 hp (2,680 kW), and could generate a tractive effort of 92,000 lbf (410 kN) when starting, and could generate a tractive effort of 82,100 lbf (365 kN) at 11 mph (18 km/h).

No. 8800 would be renumbered into what had eventually became Southern Pacific No. 7457.

Southern Pacific No. 7457 was eventually passed onto the Union Pacific Railroad when Southern Pacific and its parent company Rio Grande Industries had merged into Union Pacific. It was officially retired on February 7, 2001, and was donated to the Utah State Railroad Museum where it was placed on static display.
