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. Similar in appearance to its predecessor, theEMD
F3, the EMD F7 was a 1500 hp multi-purpose locomotive. Although
originally promoted as a freight-hauling unit by EMD, the F7 was also used
in passenger service hauling such trains such as theSanta
Fe Super Chiefand the Great
Northern Empire Builder. The F7 was the fourth model in GM-EMD's highly
successful F-unit series, and was for a long time (until the introduction of
SD40-2freight unit) was the best selling Diesel-electric locomotive ever
The Kato EMD F7 comes in both A and B (cabless) variations, and is retooled
from earlier variations of the F-unit locomotive chassis to make it DCC
friendly. Passenger units can be identified by their Steam Generators vs.
freight units which lack this detail.
