There is an alternate story of how the Nickel Plate Road got that name. When William Vanderbilt sought to purchase the NYC&StL, to remove it as a competitor with his New York Central, the price, which he was quoted was, in his view, so exorbitant that he exclaimed, "My God! Your railroad must be nickel-plated!"
In 1927, the Nickel Plate Road was part of a group of railroads controlled by two brothers, Oris and Mantis Van Sweringen. Along with the Nickel Plate Road they controlled the C & O, the Pere Marquette and the Hocking Valley Railroad. The Van Sweringens established the "Advisory Mechanical Committee", which represented the best design talents from the four railroads.
This committee, after exhaustive studies and tests, used the most favorable ratios, proportions and characteristics of the Erie Railroad's 2-8-4 of 1927, and enlarged it into the famous C & O Class T-1, 2-10-4, which were built by Lima in 1930. In 1934, the process was applied in reverse from the 2-10-4 and the equally famous Nickel Plate Road "Berkshire" Class S, 2-8-4 resulted.
In 1934, the NKP took delivery of fifteen of the new "Berkshires" from the American Locomotive Company. These new locomotives were perfectly suited for the NKP and with them they set record after record. In all the NKP bought eighty "Berkshires", fifteen from ALCO and the balance from Lima Locomotive Works and numbered them 700 through 779.
These locomotives had 69" diameter drivers, 25" x 34" cylinders, a 245 psi boiler pressure, they exerted 64,135 pounds of tractive effort and each weighed between 261,100 to 266,030 pounds.
There are six surviving NKP 2-8-4 "Berkshire" type locomotives. They are: number 755 at the Conneaut Railroad Historical Museum in Conneaut, OH, number 757 at the Railroad Museum of Pennsylvania in Strasburg, PA, number 759 at Steamtown National Historic Site in Scranton, PA, number 763 at the Virginia Museum of Transportation in Roanoke, VA, number 765 at the Fort Wayne Railroad Historical Society on Edgerton Rd in New Haven, IN and number 779 at Lincoln Park in Lima, OH

Alco delivered the first 15 S (700-714), works numbers 68646-68653 in September 1934, 68654-68658 in October, and 68659-68660 in November.
Eight years later, Lima began producing three more sub-classes, which differed from the S class in little more than weight.:
S-1 (715-739), works numbers 7860-7867 in June 1942, 7868-7874 in July,
8003-8007 in March 1943, 8008-8009 in April, and 8010-8012 in May. Weights as given in the specifications above.
S-2 (740-769), works numbers 8414-8428 in January 1944, 8663- 8670 in August,
and 8671-8677 in September. Roller bearings on the driving axles. Weight rose to 254,300 lb (115,349 kg) on the drivers, 440,800 lb (199,944 kg) for the engine, and 361,700 lb (164,065 kg) for the loaded tender.
S-3 (770-779), works numbers 9371-9373 in March 1949, 9374-9376 in April, and 9377-9380 in May. Weight on drivers 266,000 lb (120,656 kg), engine weight 444,300 (201,531 kg), loaded tender weight 364,520 lb (165,344 kg).
Firebox had two thermic syphons offering a total of 98 sq ft (9.3 sq m) of heating surface and two arch tubes with an additional 19 sq ft (1.75 sq m). Piston valves measured 14" (356 mm) in diameter, had 8" (203 mm) of travel, a lead of 3/16" (5.1 mm), and lap of 1 11/16"(42.9 mm).
The NPS study notes that William Black designed several of the best-known and most highly regarded freight engines of the Superpower era. After designing the Erie's 2-8-4s, he moved to the Chesapeake & Ohio and drafted the lines for the C&O's T1 2-10-4s (which would be duplicated by the Pennsylvania as their J1s). He headed the Van Swearingen Roads' Advisory Mechanical Committee, which oversaw design for the Chessie, its subsidiary the Hocking Valley, the Nickel Plate, and the Pere Marquette.
The Nickel Plate's Berkshire design emerged from the AMC in 1934 as a "mathematically scaled-down version of the C&O's 2-10-4." The NPS account quotes Gene Huddleston's verdict that the S class was "the greatest 2-8-4 ever to take the rails."
All of the S class had Worthington Type 5 SA feed water heaters, Elesco Type E superheaters, Standard Type MB stokers, Precision Type F-3 reverse gear, and 14" (356 mm) piston valves.
See Railfan & Railroad, March 1994, for a long article by Rich Melvin in which he recounts excursion runs with 765 that demonstrate just how powerful this class was. Melvin underscores the slogan coined by Lima's Will Woodard to explain the SuperPower concept: "Horsepower at Speed." The article contains an excellent analysis of the strengths of a steam horsepower curve (there's more the faster you go) and diesel horsepower (there's plenty at the low end, but the system reaches its upper limit at a speed well below an equivalent steam engine).
