Lima Locomotive Works' engineer William E. Woodward started with a New York Central Class H-7 "Mikado" type locomotive and added a larger firebox, creating an experimental Class H-10 "Mikado". He then went one step further and designed a locomotive with a 100 square foot firebox. This larger firebox required a four-wheel trailing truck to support it. The resulting locomotive was designated Class A-1, and it was the first 2-8-4.
This new 2-8-4 locomotive was sent to the Boston & Albany Railroad by Lima in the early spring of 1925 for tests on that railroad. In several test runs over a division of the railroad that crossed the Berkshire Hills, the demonstration locomotive, which carried road number "1" hauled up to 2500 tons. The most dramatic test occurred on April 14, 1925. A Class H-10, 2-8-2 "Mikado" type steamed eastbound from the Selkirk Yard pulling a 46 car, 1691 ton, train. About 47 minutes later the Class A-1 demonstrator led a 54 car, 2296 ton, in the same direction. The demonstrator Class A-1 arrived at North Adams Junction ten minutes ahead of the Class H-10. Soon after these impressive tests, the Boston & Albany ordered forty-five of these new locomotives. Being the first railroad to use this new wheel arrangement the B&A chose to call them "Berkshire" type.
Lima put its Class A-1 demonstrator on the road and sent it across the country to sell this new class of locomotive. Wherever it went the Class A-1 established new records. This locomotive was later shipped to the Illinois Central Railroad as part of its order for fifty "Berkshires" and became Illinois Central road number 7049.
After its debut in 1925, the "Berkshire" type locomotive continued to be improved by locomotive builders and the various railroads that used them. These heavy-duty main line locomotives were used by many railroads. Notably among them were the Boston & Albany Railroad, the Chesapeake & Ohio, the Erie Railroad, the Illinois Central Railroad, the Nickel Plate Road and the Pere Marquette Railroad.
Twenty of the "Berkshire" type locomotives exist today: 2 from the Pere Marquette, 6 from the Nickel Plate Road and 12 of the C & O's 2-8-4 locomotives, which they called "Kanawhas".
There are also two tenders that were used on "Berkshire" type locomotives that have survived. They are both from the L&N. One was the tender from L&N number 1966 and it is now at the Southern Railway Museum in Duluth, GA and the other is the tender from L&N number 1985 and it is now at the Kentucky Railway Museum in New Haven, KY.
