History[]
Built by Alco for the Milwaukee Road between 1937-1938. They were used to pull the Hiawatha, along with the Class A 4-4-2, and also on other passenger trains on the Chicago-Twin Cities route, going from Chicago IL to Madison WI. Like the class A, the F7s were built streamlined from the ground up. Each had both a longbell 3 chime whistle an air horn, with the whistles being removed around the time the mars lights were added, and the horns relocated on the side of the locomotive towards the front. The F7 is known to have been the Fastest US steam locomotive in the USA, being able to go over 120MPH and there is an unconfirmed rumor of it reaching 125MPH. However, by 1951 all had been scrapped.
