Southern Pacific cab-forward 4-8-8-2 No. 4246

In 1928, the Northern Pacific went shopping for a locomotive that could eliminate doubleheading on the eastern end of its Yellowstone Division between Mandan, N.Dak., and Glendive, Mont.

Union Pacific 4-6-6-4 Challenger No. 3976

Better than most railroads, perhaps, the Union Pacific understood fast freight service. With an expansive network of lines spread across the western states, the railroad had to maintain fast schedules in order to remain competitive. Mindful of this, UP purchased the first heavy fast freight locomotives: unique three-cylinder 4-12-2s, built by Alco from 1926 to […]

The Berkshire: Fast-Freight Legend

Pittsburgh & Lake Erie A-2a 2-8-4 Berkshire

In 1920, when American railroads emerged from 26 months of government control, the prevailing philosophy of freight-train operation was to hang as many cars as possible behind a locomotive and send it out to drag its way along the line. Three locomotive types were ideal for drag freight: 2-10-2, 2-6-6-2, and 2-8-8-2. The 2-10-2 and […]
