Data from [] (20 June 2003, last accessed 24 December 2014), aka the Longhorn & Western Railroad. See also DeGolyer, Volume 80, pp. 18+. See also Locobase 8486 for a summary description of Baldwin's industrial saddle tankers. Works number was 58555 in July 1925.
Data from Railroad & Engineering Journal, Vol LXIII (Vol 3, new series), (December 1889), p. 544. Boiler pressure is an estimate. Works number was 1067 in August 1889, 1107 and 1110 in November, 1204 in August 1890.
This were compact switchers that Carnegie used in the steel works that dotted the Western Pennsylvania. The narrow-gauge industrial railway had curves as tight as 40-ft radius, which called for the short wheelbase. Porter started delivering a revised version with 9 1/2" cylinders (241 mm) in 1891. The initials in the company's name stood for Henry Kirke Porter.
