The LRM & W was incorporated in 1907 to build a road from Little Rock to Cold Spring, Ark, a distance of about 25 miles. It served the interests of A J Neimeyer Lumber Company. In 1916, the railroad had 2 locomotives and 90 cars in operation. The line was rock ballasted and laid with 60 lb/yard (30 kg/metre) rail.
The Interstate Commerce Commission's Tap Line Case summary outlines the railroad succinctly: "It is important to observe that the tap line parallels the line of the Rock Island, which is at no point more than 5 miles away. The intervening country is hilly and broken. Three towns are mentioned on the record as being reached by the tap line. Becker is a sawmill settlement, its only other industries being a brick plant and the penitentiary; at Carnes there is a small hardwood mill, which cuts hard-wood lumber for the Neimeyer Lumber Company, at a charge of $3 per 1,000 feet; and Maumelle, otherwise known as Douglas, is apparently only a logging camp. There are two or three small stave shippers on the line."
The 101 didn't serve all that long as the LRM & W's Ten-wheeler--the railroad folded in 1921 when the timber stands had been harvested, a year after the engine was sold to Choctaw Lumber.
