Carnegie Phipps & Company / Comal Power Company 0-4-0 "Switcher" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 5588)

Data from http://www.txtransportationmuseum.org/collection-1925-baldwin-steam-locomotive.php (20 June 2003, last accessed 24 December 2014), aka the Longhorn & Western Railroad. See also DeGolyer, Volume 80, pp. 18+. Works number was 58555

This little saddle-tanker served New Braunfels, Tex rail contractor United Gas Improvement Contracting Co first and was sold to the San Antonio Public Service in 1927, presumably at the end of the construction of a new line or lines. In 1942, the SAPS sold the 1 to the Comal Power Company, which operated it briefly, then put it on display.

The Texas Transportation Museum site notes that Comal painted the engine every year. After 40 years, "...this had a 'cocooning' effect and kept the engine very well preserved." It's been revived several times, each time for a short period, but after short runs in 2004 and 2005 exposed a problem in the dry pipe, the 1 has not run again.

Volunteers at the TTT began restoration work on the engine with the goal of either repairing the engine for operation or sealing it properly for display, but, the TTT's website reported: "Just putting it back together is taking much longer than anyone would like. As of early 2014, only about half of the restoration work is done. The sticking point is with the newly installed boiler flue pipes. Just finding the correct tools to flare, bead and seal the tubes, which are very small by modern standards, required a nationwide search. The pipes themselves have a very specific metal composition and had to be ordered from out of state."


Class 1 (Locobase 16234)

Data from builder's card supplied as part of the Texas Transporation Museum's page on "1925 Baldwin 0-4-0 Steam Locomotive "#1", last accessed at http://www.txtransportationmuseum.org/collection-1925-baldwin-steam-locomotive.php . See also Locobase 8486 for a summary description of Baldwin's industrial saddle tankers. DeGolyer, Volume 80, pp. 18+. Works number was 58555 in July 1925.

This little oil-burning saddle-tanker was sold to United Gas Improvement Constructing Company to serve its New Braunfels generating plant. Its on-board Western Wheeled Scraper Company air dump valve was expressly proportioned to operate 20-ton air dump cars carrying coal.

Soon after its delivery, the 1 was out of job as the power plant switched to oil burning. The locomotive went on display, but wasn't fired again until 1964. Its prospects for actual museum service were repeatedly clouded by expensive difficulties encountered during attempts at restoration and rehabilitation. By 2016, work had proceeded far enough along to offer hope that the 1 would re-enter service.


Class unknown (Locobase 10797)

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.
