The Mount Tamalpais and Muir Woods Railway was a scenic tourist railway operating between Mill Valley and the east peak of Mount Tamalpais in Marin County, California, covering a distance of 8.19 miles (13.18 km), with a 2.88-mile (4.63 km) spur line to the Muir Woods.[1] The railroad was incorporated in January 1896, and closed in the summer of 1930.[2][page needed] Originally planned as a 4 ft 8+1⁄2 in (1,435 mm) standard gauge electric trolley line, the railroad was powered by a succession of geared steam locomotives.[3] Billed as the "Crookedest Railroad in the World", the line was renowned for its steep and serpentine route, winding through picturesque terrain to a mountaintop tavern providing first-class hospitality and panoramic views of the San Francisco Bay Area.[4] Despite its popularity, the railway met its demise following a fire in 1929,[5] and dwindling ridership when the automobile could finally drive to Tamalpais' summit.[6]
