Prototype - Lima Locomotive

Nickel Plate’s S-3 Berkshires represent Lima “Super Power” at its best at the end of the steam era.  Lima developed the 2-8-4 design in the 1920’s.  In 1948 when the Nickel Plate (New York, Chicago & St. Louis RR) ordered 10 Berkshires, numbered 770 – 779, all the refinements of steam at its best had been incorporated in a massive locomotive with 69” drivers, trailing a tender of classic proportions.

 

No. 779, shipped on May 13, 1949, was the last steam locomotive produced by the Lima Locomotive Works.  She was displayed as the ultimate example of modern steam locomotive design at the Chicago Railroad Fair.  NKP No. 779 logged 677,095 miles of operation and cost $187,000.00. Retired at Conneaut, Ohio, in early 1958, NKP No. 779 came home to Lima in 1963 and was put on display in Lincoln Park, Lima, Ohio.  One of her sister engines, NKP No. 765 is undergoing full restoration at Fort Wayne, Indiana and will be steaming again.

 

The 80 Nickel Plate Berkshires became famous as locomotives due to their fine performance and efficient design, but also perhaps due to the fact that they were well-proportioned, handsome machines. Trains Magazine said in March 1969 that they exemplified not only "the engines that saved a railroad" . . but the larger world of Super Power instigated by her builder and by her wheel arrangement. She had the long stroke, high pressure, big boiler, tall drivers, and generous grate area of advanced but sound design, and her modernity of measurements had been refined with force-feed lubrication, roller bearings, a feed water heater, and a division-spanning tender.

 

These 2-8-4s served the Nickel Plate principally as freight locomotives, rolling across the hills and plains of Ohio and Indiana at speeds of 50 to 70 miles per hour. Locomotive historian Richard Cook said that they "must be ranked among the most successful steam locomotives ever built.
