Data from American Locomotive Company data card Class, 280 141, supplied in October 2022 by Ellis Tammelleo's Locomotive Dossier on Google Drive. See also S. David Carriker, The Roster of the High Point, Thomasville & Denton Railroad, dated 1 January 1989, supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange collection. Works number was 65187 in June 1924.
(Note on provenance: This engine and four more originally entered the production line in Paterson, NJ as a quintet destined for the EF de Dourado in Brazil. When the class was almost ready for shipment, the railway cancelled the order and Cooke listed them as stock. Although the data is the same throughout, Locobase offers entries for all five because of their varied histories. See Locobase 16603, 16632, 16633, 16634, 16635.) Locobase won't reproduce all the details, but it's worth cataloging all the different railroad names (most "colloquial"or informal, as Carriker terms them) bestowed on this little 21-mile long (33.8 km)--later 35 miles (56.3 km--North Carolina line: North Carolina Mining, Manufacturing & Development Company (1903, aka Thomasville & Denton Railroad; Carolina, Glen Anna & Pee Dee Railway & Development Company (1906) aka Thomasville, Glen Anna & Pee Dee RR; Thomasville & Glen Anna RR; Carolina Valley Railway (1907); Piedmont Railway (1909); merged with Carolina & Yadkin River Railway; High Point, Thomasville & Denton (1923) Harold Pollitt's Collection of HPT&D data states this small superheated Consolidation was originally intended for the Estrada Ferro de Dourado in Brazil, but was never delivered. Acquired by the recently renamed HPT&D, it operated on the railroad for almost 25 years before being sold to locomotive rebuilder/reseller Georgia Car & Locomotive in 1947. GC&L gave it stock # 876. GC&L and Birmingham Rail & Locomotive (stock 1516) jointly sold the engine in June 1947 to Tuskegee Railroad.as their number 750. A 1953 showed the 750 as "out of service."
