Some good news, some bad news in the specifications for this small superheated Ten-wheeler. On the one hand, it would be rolling on 50 lb/yard (25 kg/metre) rail. On the other hand, the rail was laid on soft ground. 8" (203 mm) piston valves admitted the superheated steam to the cylinders. (NB: Baldwin also supplied a 2-4-2T engine with 13" x 18" cylinders [331 x 457 mm] in the same year, but that page is missing from the DeGolyer Library's copy of Volume 79.)
The railway opened in 1927 as a branch that began at Buchans Junction on the Anglo-Newfoundland Development company's rails and headed 19 miles (30.6 km) int ot the "windswept interior" to a newly established copper mine at Millertown. The line remained open for decades and operations expanded in 1957 when the BMC bought the MIllertown Railway (which ran to Millertown and Lake Ambrose). Closure came in 1976, at which point, says the Buchans Railway article, "Buchans became a ghost town."
