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.

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.
