Angelina & Neches River 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 103 (Locobase 11420)

Data from "Locomotive Building," The Railroad Gazette, Vol XLII, No 25 (21 June 1907), p 916; and DeGolyer, Volume 31, p. 15. See also John Troesser, "The Angelina and Neches River Railroad: An East Texas Short Line Railroad" found on TexasEscapes.com (http://www.texasescapes.com/TexasRailroads/ShortlineRR/AngelinaAndNechesRiverRailroads.htm). See also Bob Bowman, "An Unlikely Partnership: Angelina and Neches River Railroad" at http://www.texasescapes.com/BobBowman/An-Unlikely-Partnership.htm . Works number was 31505 in August 1907.

The Angelina County Lumber Company was based in Keltys, Texas and this skinny-rail Mogul was ordered just as the railway was converting to standard gauge.


Class 106 (Locobase 11098)

Data from Logging Locomotives 1913 (Philadelphia, Pa: Baldwin Locomotive Works, 1913), p. 15; and DeGolyer, Volume 43, pp. 237+. John Troesser, "The Angelina and Neches River Railroad: An East Texas Short Line Railroad" found on TexasEscapes.com (http://www.texasescapes.com/TexasRailroads/ShortlineRR/AngelinaAndNechesRiverRailroads.htm). See also Bob Bowman, "An Unlikely Partnership Angelina and Neches River Railroad" at http://www.texasescapes.com/BobBowman/An-Unlikely-Partnership.htm . Works number was 39351 in February 1913

The Angelina County Lumber Company was based in Keltys, Texas, but this Mogul actually served the A&NR. The A&NR linked Keltys with Manton with an eight-mile(12.9 km) line. As John Troesser observed, the cut-over timberland in the area inspired thoughts of establishing peach orchards, "...but these plans literally failed to bear fruit." Put in sevice as a narrow-gauge line, the road was rebuilt in 1906 and extended from Nacalina to Chireno in Nacogdoches County. This one locomotive constituted its entire standard-gauge motive-power stud until the company bought another in 1919; see Locobase 14708.
