Temple Lumber Company 2-8-2 "Mikado" Locomotives in the USA

Class 18 (Locobase 13853)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University C-7626 as archived at The History Center of Diboll, Texas at [], last accessed 12 February 2012. DeGolyer, Volume 71, pp. 402+. (Thanks to Steve Low for his 17 July 2019 email correcting the superheated variant's Locobase number.) Works number was 55382 in May 1922.

Locobase recommends reviewing the full specification to see what Baldwin described as standard practice in terms of materials, procedures, techniques in the mid-1920s - fascinating. See also Locobase 13854 for a superheated variant that arrived about 8 years later.

Class 20 (Locobase 13854)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University 30 D 23 as archived at The History Center of Diboll, Texas at [], last accessed 12 February 2012. See also DeGolyer, Vol 80, pp. 433+. Works number was 61193 in December 1929.

Locobase recommends reviewing the spec to see what Baldwin described as standard practice in terms of materials, procedures, techniques in building a logging Mikado in the late-1920s. Even though this was quite a bit larger than most logging 2-8-2s, the 20's construction had specifically to meet both State of Texas regulations and the American Logging and Sawmill Safety Code.

The relatively generous amount of superheat dictated piston valves, so the 20's cylinders were served by piston valves measuring 10" (254 mm) in diameter.

See also Locobase 13854 for a saturated predecessor that arrived in 1922.
