Tunnel Number 6, or the Summit Tunnel, is a railway tunnel between Santa Margarita, California and San Luis Obispo, California.[1] It is the longest tunnel along the Union Pacific Railroad Coast Line at 3,610 feet (1.10 km) in length and is wide enough to carry a single track.[2] The tunnel under the Cuesta Pass represents the highest point along the line at 1,323 feet (403 m) above sea level.[3]
The tunnel was constructed between 1893 and 1894 by the Southern Pacific Railroad. It was enlarged between 1940 and 1959.[2] One daily passenger train, the Coast Starlight, operates through the tunnel.
