The Lehigh Valley Railroad needed more motive power to handle the surge during World War I and bought Seventy-six "Santa Fe" type locomotives from the Baldwin Locomotive Works. Forty were delivered in 1917 and the other thirty-six came in 1919. These locomotives were designated as Class R-1 and given road numbers 4000 through 4075. They had 63" diameter drivers, 29" x 32" cylinders, a 200 psi boiler pressure, exerted 72,620 pounds of tractive effort and each weighed 370,000 pounds. The firebox with its 100 square foot grate area was designed to burn a combination of anthracite and soft coal.

These locomotives were bought for slow-freight services between Manchester, NY and Sayre, Pa, a distance of 88 miles with a ruling grade of .4%. Each of these R-1s replaced two "Consolidations". In this service they were rated at 4,000 tons and 6 1/2 hours.

After the war, as traffic diminished and the needed for fast freight returned the 2-10-2s proved too slow for main line traffic and the LV sold eleven of them to the Hocking Valley in 1920 and then another five in 1923. It rebuilt twenty of them to be 2-8-2s. These remaining forty, numbers 4000 through 4039 were used until the end of steam.

There are no surviving LV 2-10-2 "Santa Fe" type locomotives.

Firebox burned combination of anthracite and soft coal. Wagon-top boiler had a firebox with a combustion chamber that added 116 sq ft (10.8 sq m) to the heating surface area and 59 sq ft (5.5 sq m) of arch tubes. Fourteen-inch (356 mm) piston valves supplied steam to the cylinders. Thirty of the first forty engines had Walschaert valve gear, the other ten had Baker. Ragonnet power reverse. Economy front truck, Rushton inside-journal rear truck. The last forty locomotives saw an increase in permitted adhesion weight to 294,000 lb (133,356 kg); all of this set used Walschaert gear.

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 the last sixteen of these low-drivered Santa Fes to the Hocking Valley in Ohio in April 1920 and 1922 (see Locobase 477 for the post-LV configuration.) The LV converted 20 more R-1s to N-6 class 2-8-2s in 1928-1929.
