The prominent Elesco feedwater heater gives Pacific No. 4933 an impressive and powerful look in this photo taken by Robert Graham of St. Paul, Minnesota, somewhere on the "Big Four," before her 1936 renumbering from CCC&StL No. 6533. The last 4-6-2s delivered to the New York Central System before the appearance of the Hudson type, the engines of class K5 were powerful enough, exerting 37,650 pounds of tractive force, with a booster adding 9,700 pounds. No. 4933 was a representative of class K5b, built by American Locomotive Company in 1926-27. She had 79-inch drivers, cylinder dimensions of 25x28 inches, and a boiler pressure of 200 pounds per square inch. Like most members of this class, No. 4933 weighed 302,000 pounds. A few members of class K5 weighed more, and were the heaviest of the New York Central's Pacifics, while a few others had a slightly higher boiler pressure and tractive effort. But No. 4933 can be taken as a good representative of this last group of 4-6-2s to be added to the Central's fleet.

Two K5b sisters, Nos. 4915 and 4917, received streamlined shrouds and disc drivers in 1936, as shown in a Gary Overfield photo in George Elwood's collection. They powered the Detroit-Cleveland Mercury, later the Cincinnati-Chicago James Whitcomb Riley.
