The Class A-1 Berkshire is a 2-8-4 steam locomotive first built in 1925 by the Lima Locomotive Works. The design was initially intended to improve on the company’s USRA Mikado design (2-8-2), which was deemed to lack sufficient speed and horsepower. This was addressed by the inclusion of a larger, 100-square foot firebox that required an extra trailing axle, giving the locomotive its distinctive 2-8-4 wheel arrangement.
The Berkshire locomotive was so named for its testing location on the Berkshire Hills of the Boston & Albany Railroad. After the Class A-1 successfully outperformed a Class H-10 Mikado, the Boston & Albany Railroad became the first to order the new Berkshires. Over 600 were built by Lima Locomotive Works, the American Locomotive Company and Baldwin Locomotive Works. A total of nineteen different railroads purchased Berkshires, including the Erie Railroad, who owned 105 Berkshires, more than any other railroad; the Chesapeake & Ohio Railway, who nicknamed theirs the Kanawhas, and the Louisville & Nashville Railroad’s, whose locomotives were technically designed as Class M-1 but were referred to as “Big Emmas.” Editor’s Note: Over the years, there has been quite a bit of speculation as to the immense power generated by a steam locomotive. In the attached link, Mr. Rich Melvin’s interview will interject some perspective on this long sought after answer.
