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, over 200,000 passenger trips through LAUS each weekday are expected to occur. The Link Union Station Project (Link US or project) is proposed to meet the multi-modal transportation demands at LAUS by: increasing the regional and intercity rail service capacity of LAUS;

  • improving schedule reliability at LAUS through the implementation of a run-through tracks configuration and elimination of the current stub-end tracks configuration;
  • preserving current levels of freight rail operations;
  • accommodating the planned HSR system in Southern California;
  • increasing the passenger/pedestrian capacity; and
  • enhancing the safety of LAUS through the implementation of a new passenger concourse.

The Link US Project comprises several key components:

  • New lead tracks, elevated rail yard, and platforms
  • New concourse-related improvements, including new escalators, elevators, and canopies
  • New run-through tracks (including the possibility of a loop track) south of LAUS over US-101
  • Accommodation of CHSRA’s planned HSR system on common infrastructure¹ to support future HSR trains
  • New rail communications, signals, and safety improvements
  • Off-site improvements to BNSF Malabar Yard

The Link US team comprises a number of agency partners working collaboratively to make this project a success. The Los Angeles County Metropolitan Transportation Authority (Metro) is the local project sponsor, lead agency under the California Environmental Quality Act (CEQA), and a joint-lead agency under the National Environmental Policy Act (NEPA). CHSRA serves as the lead federal agency under NEPA, as well as other federal environmental laws for the project, pursuant to 23 United States Code² (U.S.C.) 327 and a Memorandum of Understanding (MOU) between the Federal Railroad Administration (FRA) and the State of California, executed on July 23, 2019. Other federal, state, regional, and local agencies with responsibility to advise and provide feedback throughout the project include the California State Transportation Agency (CalSTA), the Southern California Regional Rail Authority (SCRRA), Amtrak, Los Angeles – San Diego – San Luis Obispo (LOSSAN) Rail Corridor Agency, Caltrans, and the Cities of Los Angeles and Vernon.


1 Common infrastructure corresponds to structures and embankments to support run through service for Metrolink, Amtrak, and future HSR trains.
