In 1915, the Baldwin Locomotive Works delivered a "Mikado" type locomotive to the Caddo & Choctaw Railroad in Arkansas, and the railroad numbered it #4 and named it "R. L. Rowan". In the early 1920s this locomotive was sold to the Choctaw River Lumber Company, which ran it as #4. The locomotive was sold again in 1924 to the United Mining and Smelting Company in Mexico, which gave it number 2069 and later in 1924, it was sold the Mc Cloud River Railroad.
The Mc Cloud River Railroad already had one 2-8-2, which it bought new from Baldwin in 1914 and had assigned it number 18. The newly acquired locomotive was a close twin to number 18 and it was given road number 19.
The nearly identical sisters served on the McCloud River Railroad in a roster of similar sized 2-8-2 and 2-6-2 locomotives until bumped from service by new Baldwin diesels. In 1953, surplus after twenty-nine years of service, the #19 was sold to the Yreka Western and is being used today for steam train excursions.

Data from DeGolyer, Vol 52, pp. 375+. See also Kenneth L Smith, Sawmill: The Story of Cutting the Last Great Virgin Forest East of the Rockies (University of Arkansas Press, 1986), esp. pp 53-58. Works number was 52191 in August 1919.
This Mikado's superheated boiler supplied steam to the cylinders through 12" piston valves.
The 4 remained on the C & C for but a short time before being sold in 1918 to the Mexican Railway as their 105 and sent south of the border. Some time later, the Mex sold the 105 to United Mining & Smelting as their 2069. UM&S sold the 2069 in 1953 to the McCloud River, which renumbered it 19 but sold it almost immediately to the Yreka Western. The YW eventually sold the 19 in 1971 to the Oregon, Pacific & Eastern.
Data from DeGolyer, Vol 71, pp. 213+. Works number was 55565 in July 1922.
The first R L Rowan was a superheated Mikado delivered to the C&C in 1919. As Locobase notes in entry 14312, the Rowan (#4) was sold to the Mexican Railway soon after delivery. Perhaps the C&C concluded that they didn't really need superheat because when they replaced the 4 with this 2-8-2, they bought a saturated boiler and less power. They did, however, retain piston valves (10"/254 mm) to admit steam to the cylinders.
Caddo River Lumber later sold the 10 to the Warren & Saline River, which owned the 19.9 miles (32 km) of 45, 55, and 60 lb/yard (22.5, 27.5, and 30 kg/metre) rail between Warren and Hermitage, Ark. (The W&SR had another 16.4 miles/26.4 km of trackage rights.)
