Burlington Northern F9-2 BN-1

BN-1 was originally built by the Electro-Motive Division of General Motors in February 1954 as Northern Pacific F-9A #6700A. It became Burlington Northern #9800 after the merger of March 2, 1970.

After the creation of Amtrak, #9800, originally a passenger unit, was assigned to freight service and renumbered #766.

It was retired in November 1981 and was rebuilt as Rotary Snowplow Power Plant #972567. 

In September 1990 it was rebuilt by Burlington Northern’s West Burlington Shops in Burlington, Iowa into F9-2 BN-1.

The rebuild included replacing the original 1500 horsepower engine with a new 2000 horsepower 16 cylinder engine.
