The Sugarland was one of the several "Gulf Coast Lines" that were acquired by the New Orleans, Texas & Mexico in 1926. (The NOT & M was effectively acting as an agent for the Missouri Pacific.)
This was a small, freight-oriented Ten-wheeler built quite late in the 4-6-0's US career.
These Ten-Wheelers were relatively small, but so was the short line for which they were built. The light axle loading may be a clue to the branch-line demands for which these engines were built.
