Link Union Station (Link US)

Los Angeles Union Station (LAUS) is Southern California’s primary transportation hub, connecting multiple counties with a combined population exceeding 20 million people. By 2040, ridership through LAUS is forecasted to increase from roughly 110,000 to more than 200,000 passenger trips each weekday.

The Los Angeles County Metropolitan Transportation Authority (Metro) is evaluating the Link Union Station (Link US) project to address the forecasted increase in ridership, expand regional rail connectivity, and create potential opportunities for transit-oriented development. Link US plans to transform LAUS into a modern transit and mobility hub offering an improved passenger experience to meet the region’s long-term transportation needs.

Key components of Link US include:

  • Reconfiguration of the “throat” (station entry tracks) and “rail yard” (station arrival and boarding area)
  • A new, expanded passenger concourse with retail, food services, passenger waiting areas, and other transit-serving amenities
  • New run-through tracks over the US-101 freeway to provide one-seat rides to major destinations in Southern California
  • A new loop track to provide operational flexibility
  • Accommodation of future transportation options, including the California High-Speed Rail (HSR) project

The project will transform LAUS from a “stub-end,” or dead-end station, to a “run-through” station by extending tracks south over the US-101 freeway. Currently, as a “stub-end” station, all commuter and intercity trains enter and exist LAUS through a five-track “throat” or station entry tracks located north of the station. This results in a 20-minute or longer idle time for trains at the station platform area. Transforming the existing stub-end tracks to run-through tracks is anticipated to reduce idling times to five minutes or less.

The Link US Team is comprised of a number of agency partners all working collaboratively to make this project a success. Although Metro is spearheading the project, other federal, state, regional, and local agencies have a responsibility to advise and provide feedback throughout the project. These agency partners include the Federal Railroad Administration (FRA), the California High-Speed Rail Authority (CHSRA), the Southern California Regional Rail Authority (SCRRA, also known as Metrolink), Amtrak, Los Angeles – San Diego – San Luis Obispo (LOSSAN) Rail Corridor Agency, Caltrans, and the City of Los Angeles.
