Division 20 Portal Widening & Turnback Facility Project

The Division 20 Portal Widening and Turnback Facility Project aims to accommodate increased service levels on the Metro B Line (Red)/D Line (Purple) . To achieve this, Metro is planning facility improvements to the Division 20 Rail Yard, located within the Arts District in downtown Los Angeles. Improvements include: widening of the heavy rail tunnel portal south of the US-101 freeway, a new turnback facility and expansion and reconfiguration of rail storage tracks. With these improvements, new tracks and switches will allow for improved service times at Union Station and throughout the Metro B Line (Red)/D Line (Purple) system.

Presently, the Metro B Line (Red)/D Line (Purple) carry over 140,000 passengers each day. Ridership is expected to grow by 49,000 following the completion of the Purple (D Line) Extension to the future Westwood/VA Hospital Station ( as described in the Final Environmental Impact Statement for the Metro Purple (D Line) Extension ). Many B Line (Red)/D Line (Purple) trains switch tracks before entering Union Station, which is the reason that some trains operate more slowly coming in and out of the station. This project will allow switching to take place after riders get on or off trains, allowing for faster service times. It will also help to ensure safety and reliability on the system, a sufficient capacity to serve future passengers and a more effective operation of Metro’s expanding subway network.

Now that the project is under construction, questions or comments regarding rail construction in the Division 20 Rail Yard can be sent to the Purple (D Line) Extension Project at . Calls can be made to the Purple (D Line) Extension's 24/7 hotline at 213.922.6934.

2012: The Metro Board certified the Final Environmental Impact Report (FEIR) certified for the Westside Subway Extension Project (Purple Line Extension), which identified the need for additional storage capacity at the Division 20 Maintenance and Storage Facility.

2017: Metro finalized an Initial Study/Mitigated Negative Declaration (IS/MND) for the Red/Purple Line Core Capacity Improvements project, the former name for the Division 20 Portal Widening and Turnback Facility Project.

Late 2017- 2018: To address design refinements, Metro conducted and completed an environmental review of the Division 20 Portal Widening and Turnback Facility Project. In October 2018, the project’s Final Environmental Impact Report (FEIR) was approved by the Metro Board of Directors.

Late 2018: Preconstruction efforts underway including demolition of existing structures, environmental remediation, and site grading.

2019: Environmental Impact Report Addendum

On December 5, 2019, the Metro Board of Directors approved an Addendum to the Final Environmental Impact Report (FEIR). You can read the Board report here .

The Addendum addresses changes to the Project and proposes revised mitigation measures that are necessary due to the changes to the Project. Two changes have been identified since the FEIR was approved by the Metro Board in October 2018:

  1. The elimination of a High-Speed Rail column and ventilation shaft building and;
  2. A fire at the Citizens Warehouse/Lysle Storage Company Building and the building's subsequent demolition by the City of Los Angeles. Since the approval of the Project's FEIR, the Citizens Warehouse/Lysle Storage Company Building was severely damaged by a fire and was subsequently demolished by the City of Los Angeles due to unsafe conditions.

Since the building demolition, Metro acquired the property from the City of Los Angeles. During this phase, the site is being utilized as a temporary parking lot to support construction activities for the Project. You can see the latest construction updates for the project under the 'Construction Notices' tab above.

As Metro is only utilizing part of the site for storage tracks per the Project EIR, Metro is committed to working with community stakeholders and local jurisdictions to determine a vision for a potential project on the remaining vacant portion of the site as part of Metro's Joint Development policy.
