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. The EMD F7 was a 1500 hip multi-purpose locomotive. After the introduction of Amtrak in 1971 the AT&SF repurposed many of its F-units for freight use, swapping the traditional red War bonnets for a blue equivalent and removing their steam generators - although many still retained the original dual passenger headlights.
