K Line (Los Angeles Metro)

On November 3, 2024, the C and K lines underwent service changes to accommodate pre-revenue testing at the upcoming LAX/Metro Transit Center station, scheduled to open in 2025.The LAX Automated People Mover, which will offer a connection to the airport's terminals, will begin service at LAX/Metro Transit Center station in 2026.It travels underground in a one-mile (1.6 km) deep-bore tunnel, which transitions into an at-grade segment in the median of Crenshaw Boulevard (between 48th and 59th Streets) where trains run synchronized to existing traffic signals.South of there, the route emerges from the tunnel and enters the Harbor Subdivision right of way, which runs parallel to Florence Avenue and Aviation Boulevard.The line mostly operates at-grade in this exclusive right-of-way, briefly transitioning onto elevated viaducts to cross over major thoroughfares including La Brea Avenue and I-405.North of Century Boulevard, LAX/Metro Transit Center station will be at-grade and serve as the new western terminus of the C Line and function as a transfer point to the currently under construction LAX Automated People Mover.The line then briefly enters an open trench as it passes close to the LAX runways[4] before splitting from each other at a wye west of Aviation/LAX station.Studies in 1984 and 1988 outlined routes from the Aviation/LAX station, running northeast to LAX and Westchester, similar to later plans for the second phase of the Sepulveda Transit Corridor.[16] The new line was championed by State Senator Diane Watson and County Supervisor Yvonne Brathwaite Burke, both representing portions of the corridor.[35][36] The approved plan would have incurred higher operating expenses but board members argued it would retain better transfer opportunities for South Bay residents.[39] On June 22, 2023, Metro's board of directors officially approved the implementation of Option 2 based on staff recommendation and public opinion.[38][44][7] Metro is currently working on the initial environmental study of a corridor extension of the K Line from its Redondo Beach terminus toward the southeast.The C Line Extension would roughly follow the Harbor Subdivision ROW into the South Bay, to the Torrance Regional Transit Center (RTC).However, once light rail was selected as the preferred mode, the cost for the entire route exceeded the project budget, so part of the corridor north of Exposition Boulevard was deferred until funds became available.The K Line is operated by Division 16 (Southwestern Yard) in Westchester directly east of the northern runways of the Los Angeles International Airport, and adjacent to the future LAX/Metro Transit Center station.
To prepare for a LAX extension, Metro built two concrete ramp stubs west of the Aviation/LAX station.
