  PROTOTYPE SPECIFIC INFORMATION

  The F-units were the most successful first generation road (main line) diesel locomotives in North America, and were largely responsible for superseding steam locomotives in road freight service. Before this, diesel units were mostly only built as switcher locomotives, and only used in rail yards.
