Ten-wheeler No. 840, renumbered to 1253 in 1948, pauses at Yorktown Heights, New York on the NYC's Putnam Division in 1937. Originally numbered 2127 when erected by American Locomotive Company in 1907, she and her sisters were reclassified from F2e to F12e when superheated, and went through a series of modifications during their careers including the application of Baker or (as above) Walschaert valve motion. These elderly 4-6-0s that served commuters on the Putnam Division were some of the last steam locomotives to operate on the Central's eastern lines, No. 1253 being among the last to be retired at the end of 1951. Their dimensions included 69-inch drivers, 22x28-inch cylinders, and 200 pounds per square inch of boiler pressure. They weighed about 213,000 pounds and developed a tractive effort of 31,900 pounds. This view of No. 840-1253, by an unknown photographer, was provided by Wayne Koch from his collection.
