Steam locomotive profile: 4-8-2 Mountain
BY Neil Carlson The development of the 4-8-2 grew out of the need for a locomotive with greater power than the Pacific to handle heavy passenger trains in mountainous terrain.

Steam locomotive profile: 4-8-4 Northern
Northern Pacific 4-8-4 No. 2662 storms up the 1.8 percent grade at Muir, Mont., in 1947. Warren R. McGee With the general speed-up of passenger train schedules in the 1920s, the need arose for a more powerful version of the 4-8-2.

Steam locomotive profile: 2-8-8-2
A scant three years after Alco introduced the Mallet to America (with the delivery of B&O’s sole 0-6-6-0 in 1904), the Erie took delivery of three camelback 0-8-8-0 Mallets – the first eight-coupled Mallets, also built by Alco – and put them to work as helpers on Gulf Summit in New York state. Southern Railway […]
Steam locomotive profile: 2-8-8-4 Yellowstone
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.
