The Ace & Acme Lumber Company was formed in 1880 to cut and mill lumber from the Sandwich mountains between Campton and Parsons Vale. By 1890, they had built a logging railroad to deliver raw timber to the Acme mill in Campton and the Termite mill in Parsons Vale. By 1900, the A&ALCo lumber plots were logged off and the railroad was mainly shut down in favor of doing fine milling on rough cut timber from other mills at the Termite mill.

In 1908, the Lincoln & Concord Railway purchased the A&ALCo to provide a route between Campton and Parsons Vale. When the line was electrified, logging operations were restarted north of the Bearcamp River and continued until 1937.
