Link Union Station (Link US)

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

Project Components Aerial Map

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.


Approximately 110,000 passenger trips are made through LAUS each weekday. Forecasted population and employment growth will create additional demand on bus and rail resulting in over 200,000 passenger trips through LAUS each weekday by 2040, not including trips from the future California HSR services.

Link US enables LAUS to accommodate future demands by increasing peak capacity, improving regional rail connectivity, and providing connections to more transportation options. Link US will also provide an improved passenger experience by reducing travel times and improving access and circulation, while potentially reducing greenhouse gas emissions from idling trains.

Project benefits include:

  • Improved transit connectivity
  • Enhanced passenger experience
  • Improved regional connectivity
  • Reduced train idling times
  • Future development
  • Generate 4,500 jobs per year
  • Improved pedestrian access
  • Increased rail service capacity
  • Improve US-101 and local roadways

Concourse Design Options

Link US proposes a new expanded passenger concourse that will provide potential opportunities for a wide array of retail and transit-serving amenities, transforming LAUS into a world-class transit and mobility hub for visitors, tourists, and our communities. As envisioned, the new passenger concourse would connect with the Patsaouras Bus Plaza to the east with the historic Union Station to the west.

There are two passenger concourse options under study that would allow passengers to access the train platforms from either an above-grade or at-grade concourse. The at-grade passenger concourse option would be located below the rail yard while the above-grade option would be located above the yard. The environmental document will analyze the two concourse options. The two preliminary concept videos below depict the two concourse design options under study. The draft design concepts shown were created in the beginning stages of the study process, and are subject to change as the project advances.

A joint Environmental Impact Statement/Environmental Impact Report (EIS/EIR) is being prepared pursuant to the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA) to comply with federal and state environmental requirements, respectively.

There are two Build Alternatives and a No-Build Alternative being analyzed in the environmental document.

1. Build Alternative 1 – Shared Tracks

  • Up to 10 run-through tracks over US-101
  • High-Speed Rail would share 2 lead tracks with Regional Rail
  • 1 new additional lead track in the Throat area (6 lead tracks total)

2. Build Alternative 2 – Dedicated Tracks

  • Up to 10 run-through tracks over US-101
  • High Speed Rail would use separate lead tracks built specifically for HSR
  • 2 new additional lead tracks in the Throat area (7 lead tracks total)

3. No-Build Alternative:

  • Assumes LAUS and the existing stub-end tracks remain as-is

The proposed project also includes two design options for the new expanded passenger concourse:

  • Design Option A: At-Grade Passenger Concourse
  • Design Option B: Above-Grade Passenger Concourse

Please see the Concourse Options tab to learn more about the two concourse design options.

Link US Project Development Overview

The Link US project is in the early planning stages. We are currently preparing environmental studies and conceptual engineering for the project. Completion of the design will take place once the project is environmentally cleared to proceed into the final design stage. Ongoing public engagement will occur within each phase.

Anticipated Project Development Process

  • Early Planning
  • Draft Environmental Studies and Conceptual Engineering (current status)
  • Final Environmental Clearance
  • Final Design
  • Construction
  • Open for Service

Environmental Schedule

The EIS/EIR and associated technical studies are currently under agency review. The Link US Project team has been busy meeting with key agencies and stakeholders to provide updates on the status of the Link US project and discuss the alternatives under consideration.

After agency review, the public will have the opportunity to review the Draft EIS/EIR and provide comments/input that will be incorporated into the Final EIS/EIR. We are currently preparing for public release of the Draft EIS/EIR as early as Fall 2018 / Winter 2019.

Ahead of the public release of the Draft EIS/EIR, the Link US Project team will send email updates with information on how to comment and participate during the public review period.
