So the line enjoyed a brief but substantial volume of outgoing freight traffic from the Rogers White Lime Company located at Limedale. The underpass still exists and is still crossed by trains of Frisco Central Division successor Arkansas and Missouri Railroad. The AO&W went bankrupt a few years later and was bought by another startup railroad, the Kansas City & Memphis Railroad (KC&M) in early 1911. It would build from Cave Springs, a few miles west of Rogers, through Fayetteville and towards Memphis, Tennessee. In 1912 the Ozark Land and Lumber Company began construction of a 5-mile extension east of Monte Ne from the White River to the Piney community and leased the line to the KC&M. The White River bridge consisted of 780 feet of trestle and 2,152 foot steel spans, making it the longest railroad bridge in Benton County. This extension was used to haul out forestry products. The KC&M entered receivership in 1914, and in September of that year passenger service to Monte Ne ended. When the U.S. entered World War I in 1917, many railroads were seized by the United States government. The KC&M was not seized, and due to unfavorable rulings by the United States Railroad Administration and Arkansas Railroad Commission saw much of its revenue evaporate. In January 1918 Roscoe Hobbs, one of the court-appointed receivers of the KC&M, went to Washington, D.C. to provide testimony to the Senate Committee on Interstate Commerce on the effects of these decisions on small railroads. As part of that testimony Hobbs reported 215 cars from the Rogers White Lime Company and 216 cars of pit props and railroad ties being hauled on the Monte Ne portion of the railway in 1917. Hobbs was unsuccessful in having the decisions reversed, and most portions of the KC&M were abandoned by October 1918. The Monte Ne portion was used until 1919. The White River bridge survived longer and was used for horse and foot traffic before becoming unsafe. The steel spans were scrapped during World War II. In August 1901, Harvey's son Hal and brother-in-law Ernest Halliday opened a large bathhouse on Silver Springs Creek, across the lagoon from Hotel Monte Ne. The indoor pool was the first in Arkansas. It was 25 by 50 ft (7.6 by 15 m) and deep and included springboards and slides. Water from the spring flowed into the swimming pool, half of which was sectioned off and featured heated water piped in from a wood-fired boiler.
