The L&A was the 1928 amalgamation of the Louisian Railway & Navigation (LR & N) and a small Arkansas logging road known as the L & A. The LR & N that opened in 1897 was a small road whose mainline ran from New Orleans through Shreveport. The connection to McKinney, Texas (near Dallas) came in 1923. Ultimately the Kansas City Southern (KCS) acquired control in 1939, but operated the L & A as a separate entity.
During its LR & N period, it had to have been a light-rail line. The Consolidation described here had very small drivers and a low axle loading, although its boiler was reasonably proportioned. At the time of this handbook's publication, it was the railway's only 2-8-0.
