Link Union Station (Link US)

Link Union Station (Link US)

Los Angeles Union Station (LAUS) is Southern California’s largest multi-modal transportation hub, connecting six counties (Ventura, San Diego, San Bernardino, Riverside, Los Angeles and Orange) in addition to the Los Angeles – San Diego – San Luis Obispo (LOSSAN) Rail Corridor.

Key components of the Link US project include:

  • New rail communication, signals, tracks, optimized throat and railyard
  • New run-through tracks over US-101
  • New modified expanded passageway, platforms, escalators, and elevators
  • Accommodation of High-Speed Rail with a new lead track

The project will transform how the regional rail system (commuter and inter-city rail) operates in Southern California by converting LAUS from a “stub-end” station, to a “run-through” station by extending tracks south over the US-101 freeway. This could enable one-seat train rides from San Luis Obispo to San Diego. Currently, as a “stub-end” station, all commuter and intercity rail trains enter and exit LAUS through station entry tracks located north of the station. This can result in 20-minutes or longer idle time for trains at the station platform area. Conversion of the existing stub-end station to a run-through station is anticipated to significantly increase capacity for rail service while reducing train idling times.

The Link Union Station (Link US) project will address the forecasted increase in ridership from roughly 110,000 to more than 200,000 passenger trips each weekday by 2040 with a new modified expanded passageway including retail and amenities that enhances the passenger experience, create potential opportunities for transit-oriented development and transform LAUS into a world-class transit and mobility hub.

The Link US Team is comprised of a number of agency partners such as the Federal Railroad Administration (FRA), the California State Transportation Agency (CalSTA), 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 working collaboratively to bring this project to a successful fruition.

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 High-Speed Rail 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 at LAUS.

Anticipated Project benefits include:

  • Improved intrastate, intercity, and local transit connectivity with High-Speed Rail; Metrolink, Amtrak, and Metro rail; Metro and municipal bus systems; and ridesharing platforms
  • Improved regional connectivity with one seat rides to key destinations in Southern California
  • Increased rail service capacity to accommodate future demand
  • Reduced train idling times resulting in shorter wait times and fuel savings and emissions reductions per train
  • Creation of future retail and transit-serving amenities and other transit-oriented development
  • Generation of an estimated 4,500 temporary jobs per year over a 5-year construction period and 200+ permanent jobs
  • Enhanced passenger experience with proposed modified expanded passageway, retail and other amenities and new expanded platforms
  • Improved pedestrian access with enhanced mobility options and safety features
  • Improved US-101 and local roadway

Concourse Design Options

Link US 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. The proposed concourse improvements would connect the Patsaouras Bus Plaza to the east with the historic Union Station to the west.

Draft EIR

Two passenger concourse options were evaluated in the Draft EIR that would allow passengers to access the train platforms from either an above-grade or at-grade concourse. The proposed project included an above-grade passenger concourse with expanded passageway below the rail yard, and the build alternative included the at-grade passenger concourse, also located below the rail yard.

Final EIR

As a result of coordination with funding partners and public feedback during the public review of the Draft EIR, the loop track and above-grade passenger concourse were removed from the project. The expanded passageway located below the rail yard considered in the Draft EIR would be modified to provide transit-related retail, food and other amenities to create a world-class transit station and improve the passenger experience.

An Environmental Impact Report (EIR) and an Environmental Impact Statement (EIS) are being prepared pursuant to the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA) to comply with state and federal environmental requirements, respectively. The Link US Draft Environmental Impact Report (EIR) was available for public review from January 17 to March 4, 2019. The Link US project team has been coordinating with key stakeholders and agencies to respond to comments. An electronic copy of the Final EIR and appendices will be available for public viewing starting as early as summer 2019.

Draft EIR

1. Proposed Project

  • Up to 10 run-through tracks over US-101 and a new loop-track
  • High-Speed Rail trains would operate on two shared lead tracks with Regional/Intercity trains
  • One new additional lead track in the “Throat” area (six lead tracks total)
  • Above-grade passenger concourse with new expanded passageway

Proposed Project

2. Build Alternative

  • Up to 10 run-through tracks over US-101
  • High-Speed Rail trains would operate on separate (dedicated) lead tracks
  • Two new additional lead tracks in the “Throat” area (seven lead tracks total)
  • At-grade passenger concourse

Build Alternative - Up to 10 New Run-Through Tracks with Shared Tracks

3. No Project/No Build Alternative

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

Final EIR

Based on comments received on the Draft EIR and the outcome of considerable coordination with project funding partners and rail operators, the Final EIR includes the following modifications to the Draft EIR project:

  • Removal of Above-Grade Passenger Concourse
  • Removal of Loop Track
  • Removal of Construction Access Road
  • Removal of Construction Staging Areas
  • Removal of Property Takes
