Purely on looks the Northern was one of the most aesthetically beautiful steam locomotive designs ever developed. While some of these handsome locomotives would receive streamlining even without such enhancements they were still a fine looking piece of machinery with a "streamlined" tender, long sweeping boiler, symmetrical wheel arrangement, and centered headlight. The 4-8-4 gained its name from the Northern Pacific where the locomotive was first operated in the 1920s. However, of all the popular steam designs ever put into service the 4-8-4 was the most widely renamed, from "Greenbriers" on the Chesapeake & Ohio to "Westerns" on the Denver & Rio Grande Western. In many ways the 4-8-4 was the pinnacle of steam power power and technology, which utilized only a single set of drivers. Before the diesel era caught on in the late 1930s, three-dozen of largest railroads in America put the locomotive into service in both passenger and freight operations. Surprisingly, despite their size, more than a half-dozen Northerns remain in operation today and several others are preserved.

Chicago, Burlington & Quincy 4-8-4 #5632 in an all-gold livery is seen here in Kansas City on November 1, 1964 to celebrate Kansas City Union Station's 50th anniversary. She also wore solid gold earlier that year to honor the opening of CB&Q's Chicago-Aurora main line.

The decade of the 1920s (the "Roarin' '20s") saw the railroad industry experiencing unbelievable demand among the traveling public. Additionally, all-steel, heavyweight cars were replacing common and lighter wooden-built equipment. These two factors put together meant that standard designs of the day were struggling to keep up, notably the ubiquitous 4-6-2 Pacific and to some extent the 4-8-2 Mountain. Realizing this, the Northern Pacific approached the American Locomotive Company (Alco) about developing an even more powerful wheel arrangement to cope with the growing surge. After a lengthy study Alco recommended what was essentially a modified Mountain with a larger firebox for increased steam pressure and power.

This firebox would feature a 115 square foot grate area and to accommodate this the locomotive would be fitted with two rear axles instead of only one. In December of 1926 the NP took delivery of 12 of these beauties, listed as Class A and given road numbers 2600-2611. Compared to the railroad's Class Q Pacifics (it owned no Mountains) the 4-8-4s were at least 50 tons heavier, had boiler pressures nearly 50 psi higher, tractive efforts that were roughly 40% more, and could cruise at higher speeds while pulling heavier loads. Since the locomotive was first tested and used on the NP it was named the "Northern Pacific" but later shortened as just "Northern."

One particular feature that made the 4-8-4 wheel arrangement so successful was its versatility where it was just as capable of pulling a time-sensitive passenger train clipping along at 70+ mph as it was at lugging a heavy freight train over stiff grades. This versatility, along with the locomotive being equipped with some of the latest technology (including superheaters, mechanical stokers, roller bearings on all axles after 1930, and outside valve gear) made the Northern Type one of the most successful designs of the late-steam, "Super Power" era (which began during the mid-1920s) with over 1,000 built for 36 different railroads. Of special note was the development of roller bearings mentioned above.

In 1930 the Timken Roller Bearing Company worked with Alco in producing 4-8-4 Timken #1111, which featured roller bearings on all axles including the tender. After logging roughly 100,000 miles Timken successfully demonstrated the reduced wear and maintenance of roller bearings and all future steam locomotives were equipped with them (the #1111 was sold to the NP in 1933 and renumbered 2626). Some of the most well known classes of Northerns to ever operate included the Norfolk & Western’s handsome J Class, Southern Pacific’s Golden States, and New York Central’s Niagaras just to name a few (there were many others). While this steam locomotive design is best remembered as the Northern not every railroad thought such a name was appropriate for their models, such as those mentioned above.

Today, many Northern Types survive and several still remain in operation with the most famous including N&W J-Class 618 (currently in storage); Union Pacific Northern 844 (the last steam locomotive ever purchased by the UP and the only steam locomotive to never be retired by a Class I railroad); Southern Pacific Golden State 4449; Spokane, Portland & Seattle 700; C&O Greenbrier 614 (needs heavy maintenance to operate again but will hopefully one day pull the Yellow Ribbon Express); and Santa Fe Northern 3751 (and these aren’t even all still in operation!). Of all the large steamers that still remain in operation the Northerns are the most prolific so you have ample opportunities to see these beautiful ladies in action from coast to coast!
