Class H-7e Mikado No. 1977 is reported to have been the last steam locomotive to operate on the New York Central system, working out of Riverside Yard in Cincinnati with a transfer run to the Louisville & Nashville's DeCoursey Yard across the Ohio River on May 3, 1957. She appears here in this color image from Frank Fabian, no doubt during her final months of service. The H-7e class came from Alco's Schenectady works in 1920, with No. 1977 originally assigned to the CCC&StL (Big Four) as No. 6177. With 27x30-inch cylinders and 63-inch drivers, they sustained 200 pounds of boiler pressure. They weighed between 328,000 and 343,100 pounds and exerted 59,000 pounds of tractive effort. Boosters applied to some members of the H-7e class added another 10,400 pounds of tractive force, and No. 1977's cast steel trailing truck suggests she was so equipped (compare the fabricated truck on H-7c No. 2022 following, not equipped with a booster). These locomotives had 4650 square feet of evaporative heating surface, 1163 square feet of superheating surface, and a grate area of almost 60 square feet.
