Harbor Subdivision
Mostly displaced with the April 15, 2002 opening of the more direct Alameda Corridor, the Harbor Sub takes a far more circuitous route from origin to destination, owing to its growth in segments over the decades.The early 1900s would see that project eclipsed with the coming of the San Pedro Outer Breakwater and the Port of Los Angeles.By the early 1920s, owing to the development of the area's oil fields, the Harbor Sub was extended through Torrance, Wilmington and on to Long Beach.Other than sidings at "Lairport" (along the eastern edge of Los Angeles International Airport next to Aviation Boulevard at 120th Street), "Ironsides" in Torrance and the line's longest siding at the Alcoa, also in Torrance, the Harbor Sub is completely single-track without signals, compensated with track warrant control via a local dispatcher.Most of the line was purchased by the Los Angeles County Metropolitan Transportation Authority (Metro) in 1992, and freight rights are retained by BNSF.
