The Arcata and Mad River Railroad, founded in 1854, holds the distinction of being the longest-running railroad in California. Originally constructed with a distinctive narrow gauge of , it transitioned to standard gauge tracks during the 1940s. Operations were discontinued in 1983 following landslide damage. This railroad is officially designated as California Historical Landmark #842.
Union Wharf enterprises
On December 15, 1854, the Union Wharf and Plank Walk Company built a pier extending into Humboldt Bay near Arcata to support lumber shipments. The pier incorporated wooden rails topped with strap iron, laid to an uncommon narrow gauge of . Within one year, roughly of track was laid out from the wharf, initially powered by horse-drawn cars.
This line predates the Sacramento Valley Railroad (incorporated in 1853 with construction beginning in 1855), confirming its position as California’s earliest operating railroad. In 1875, the company was renamed the Union Plank Walk and Railroad Company. By that time, wooden rails reinforced with iron facilitated steam locomotive use; notably, the Black Diamond engine transported lumber from Isaac Minor’s Dolly Varden mill (established in 1872) to the pier.
This early infrastructure formed the backbone of the company’s key role in timber transportation across the region, enhancing its influence within the Redwood Empire’s logging sector.
Arcata Transportation Company
On June 15, 1878, the railroad underwent reorganization as the Arcata Transportation Company. The side-wheel steamer Gussie McAlpine was replaced by the sternwheeler Alta, and track expansion reached additional local mills. In 1881, control passed to the Arcata and Mad River Railroad. Over the next two years, rails were upgraded to 35 lb/yd T-rail and lines extended upstream to North Fork (present-day Korbel) and to the Humboldt Lumber Mill owned by the Korbel brothers. The line gained the nickname "Annie and Mary," derived from its initials.
Arcata and Mad River Railroad Company
By 1883, approximately 27 miles of track—including common carrier and private logging routes—were acquired by the Korbel family. They formally incorporated the Arcata and Mad River Railroad Company on December 29, 1891. During the late 1880s, A&MR primarily served lumber transportation for Isaac Minor Mill and Lumber Company. Its locomotive roster in 1890 included engines named Arcata, North Fork, Eureka, Blue Lake, as well as a smaller engine called Gypsy. A Baldwin locomotive named Hoopa was added by the early twentieth century.
In 1896, passenger traffic numbered 24,752 while freight totaled 6,475 short tons from four sawmills and two shingle mills. Passenger revenue represented approximately 28% of freight income. That year also witnessed a construction train collision and a tragic accident on September 13 when a train plunged through the Mad River truss bridge, resulting in seven fatalities—the first significant Humboldt County railroad disaster involving injuries. Legal actions against the Korbels did not succeed.
The opening of the California and Northern Rail line between Arcata and Eureka in 1901 rendered the Alta steamer obsolete. In 1903, ownership of Humboldt Lumber Mill and A&MR transferred to Riverside Lumber Company and Charles Nelson Steamship Company. They reinforced the wharf to support heavier locomotives rather than just lighter engines.
20th century
Following Francis Korbel's departure back to Prague, ownership of the company transferred to the Northern Redwood Lumber Company. On October 23, 1914, the Northwestern Pacific Railroad (NWP) extended its reach to the San Francisco Bay Area, assuming control over the California and Northern lines and uniting roughly half of Humboldt County's rail network.
By 1925, the logging railway was converted to standard gauge, with a complete installation of standard gauge tracks spanning 7.5 miles by the 1940s. The railroad marked its 100th anniversary on June 3, 1954, hosting a special excursion for rail enthusiasts and community members.
The 1950s saw a surge in the lumber industry, during which the A&MR serviced fifteen shippers along its 7.5-mile route. In 1956, Simpson Logging Company acquired both Northern Redwood Lumber Company and its A&MR operations. The railroad's daily car loadings per mile placed it among the highest revenue-generating railroad properties in the United States. At the time of its closure, AMR operated a fleet comprising four GE 44-ton diesel-electric locomotives alongside a single Whitcomb 80-ton diesel-electric locomotive.
During this era, shipments originating from Blue Lake included lumber and nails produced by Levitt Brothers’ lumberyard and nail factory, which supplied materials for Levittown housing developments on the U.S. East Coast.
The main NWP line suffered extensive damage from severe storms during the winter of 1982–83, resulting in a surcharge of $1,200 per car that encouraged shippers to switch to diesel trucking. This shift significantly weakened A&MR’s business viability. Operations ceased in 1983, and the line was officially abandoned on May 24, 1985.
In September 1988, the Eureka Southern Railroad acquired A&MR from Simpson Timber Company for $300,000. Service briefly resumed in 1994 through North Coast Railroad but ended permanently after landslides closed tracks in Humboldt County in 1998. The final use of A&MR occurred in 1992; all remaining infrastructure was dismantled by 1998. Although a proposal for converting the railway into a trail surfaced in 1997, progress has been minimal; nevertheless, the Blue Lake Chamber of Commerce continues to honor the railroad’s legacy annually.
Several railroad cars were manufactured by Carter Brothers, a prominent West Coast narrow-gauge equipment producer during the 19th century; one such car is preserved by the Society for the Preservation of Carter Railroad Resources.
