Data from Negative 5774, Southern Methodist University, Central University Libraries, DeGolyer Library collection of digitized Baldwin images, retrieved 26 October 2010 from [
] . Works numbers were 41512 June 1914 and 43006 in March 1916.
The A&W came relatively late to Louisiana. The Railway Age Gazette of 1 April 1910 (p. 917(reported that the railroad had located a 23-mile (37 km) line from Alexandria, La., west via Weil, Lamothe, Crane and Quadrate to Wilda, La. Maximum grade was planned to be 1/2% and maximum curvature would not exceed 3 degrees. The only water obstacle worth bridging was a the state canal. The line was later extended to De Witt.
Alas, within a dozen years, the A&W filed for abandoment. When the A&W closed in May 1925, Crossett Lumber bought the #9 and renumbered it either 102 or 103. CL later sold it to Frost Lumber Industries.
