The oldest rail line on the Northern California coast was the Arcata and Mad River Railroad Company, which served the area between Humboldt Bay and the Trinity River mines. The beginning of this line in 1954 is commemorated at the Blue Lake railroad depot. Affectionately called the "Annie and Mary", in honor of two of the railroad's employees in 1907, it is the oldest continuously operated line west of the Rocky Mountains. This railroad company is now part of the North Coast Railroad.
Arcata and Mad River Rail Road Company. Incorporated December 15, 1854, as the Union Plank Walk, Rail Track, and Wharf Company, the Arcata and Mad River Rail Road is the oldest line on the north coast. Originally using a horse-drawn car, the railroad served as a link between Humboldt Bay and the Trinity River mines. Later, locomotives were added as the line grew to serve the redwood industry.
