Prototype Information:

The F-Unit is probably the most recognized diesel locomotive in North American history. It was found on railroads from East to West and North to South. Eastern railroads favored a “Single Headlight” version of the F3, while Western railroads favored a “Dual Headlight” version.

F3 locomotives were used in both freight and passenger service. For passenger service, it was necessary for the locomotives to have a Steam Generator to provide heat and electricity in the passenger cars. In later years, many F3 locomotives originally intended for passenger services were downgraded to freight duty.

Model Information:

The Kato EMD F3 comes in both A and B (cabless) variations. All current variations of the F-unit locomotive chassis are DCC friendly. Passenger units are commonly identified by their Steam Generators vs. freight units which lack this detail. The 2014 run of CB&Q Freight F3’s have a number of passenger features, such as the straight pilot, as they began their life as locomotives pulling the California Zephyr before being repainted and repurposed as freight locomotives.
