PRR E6 Atlantic 4-4-2



History:  The class 4-4-2 Atlantics was the pace-setter for high-speed passenger service, which resulted in competition for the development of the fastest train. The E6, or "Hercules of Atlantics", second only to the K-4 in fame, was created by Alfred W. Gibbs. No. 5075 (later renumbered 1067 in 1912) was first developed in 1910 as an experimental model. Four years later, after intensive testing, several changes in cylinder diameters, the installation of superheaters, and the building of two other samples, eighty E6 locomotives were built by Juniata in 1914. This locomotive was produced amidst the development of the reknown K4 and the Pacific locomotives. It turned out to be a great investment into locomotive future; they led directly to other popular engines on the Pennsylvania Railroad, and E6 Atlantics could pull trains that would require six-drivered Pacifics.

An interesting feature of the E6 is that it contained a KW style trailing truck. The heavy frame of the KW balanced the rear of the locomotive, and the underframe of the locomotive was supported directly upon it. Steel castings were used on these locomotives; this was used on all railroad-designed classes until 1930.

E6s engines quickly became prime movers of main line limiteds. They worked closely with E3sd and K2 classes, dealing with World War I traffic. One locomotive, number 13, ran for many years on the Williamsport Division of Pennsylvania, and was considered good luck by many of its engine crews. This locomotive held the division mileage record for its time period, but was later to be replaced by K4s.

E6s worked their way down into Baltimore and changed from steam power into oil-powered locomotives shortly after World War II. In 1947 there were a total of 74 E6s engines. In contrast to all other Atlantics, the E6s never had a stoker, a feedwater heater, or power reverse. Their distinguishing characteristic was the two basic boilers that gave the trains the ability to run fast, carrying a heavy load. The locomotives also utilized a 26-inch cylinder stroke, 80-inch drivers, and 205 pounds of steam pressure.


Complete Kit and Accessories:  The locomotive and tender complete kit has all of the parts to build a working model. You may wish to add your own details or purchase our "Super Detail Kit" if available. Some models have an optional painted engineer and fireman, smoke unit kit and other assemblies available as optional equipment to compliment your kit-building needs.
