Firebox burned combination of anthracite and soft coal. Wagon-top boiler. Thirty of the first 40 engines had Walschaert valve gear, the other ten had Baker. Ragonnet power reverse. Economy front truck, Rushton inside-journal rear truck.
Bought for slow-freight services between Manchester, NY and Sayre, Pa (88 miles) where each engine replaced two Consolidations. On this service they were rated at 4,000 tons and 6 1/2 hours on a ruling grade of 0.4%.
This class changed teams as often as a journeyman ballplayer. Peace-time traffic demanded higher speeds and the LV sold off 16 of these low-drivered Santa Fes to the Hocking Valley in Ohio in 1920 and 1922; 6 of these were passed along to the Pere Marquette, but came back to the C&O after the 1947 merger. The LV converted 20 more R-1s to N-6 class 2-8-2s in 1928-1929.
