Missouri Pacific LEGACY Atlantic #5521 Atlantics ruled the rails in the first decade of the 20th Century as the premier examples of passenger power on railroads across the country. Retaining the large drivers and simple, compact designs of the century before, their balance and speed made them perfect for the passenger trains of the era. As passenger trains became longer and heavier with the conversion to steel car construction, many railroads bumped their Atlantics down to secondary trains as larger Pacifics rose up to meet the growing business. Despite their smaller size, hundreds of these locomotives continued to serve to the final years of steam operation - a testimony to sound and efficient design. Some roads like the Missouri Pacific, Pennsylvania and Southern Pacific continued to refine their Atlantics into modern, albeit compact, steam power which could rival the performance of many larger locomotives. Inspired by a Southern Pacific prototype but typical of designs on many railroads at the time, these Atlantics will be right at home in passenger service on your layout. Limiteds, locals or milk runs, wood cars or steel - the Atlantic is a perfect choice. And with its smaller frame, the Atlantic will look great on tighter curves and smaller layouts. All the LEGACY power, features, and sounds you need and want in a locomotive that won't break your curves or your budget!
