The West Santa Ana Branch (WSAB) Transit Corridor is a second decade Measure R Project.  Measure R allocated $240 million for this project.  Metro is currently conducting a Technical Refinement Study for the WSAB Transit Corridor, a 20-mile rail corridor in Los Angeles County from Union Station to the City of Artesia. The corridor is approximately 12-miles from Union Station to the Pacific Electric ROW/West Santa Ana Branch (PEROW/WSAB) in the City of Paramount and 8-miles along the PEROW/WSAB.   

Alternatives Analysis (AA) – Southern California Association of Governments (SCAG)

SCAG conducted an AA that analyzed opportunities for connecting Los Angeles and Orange Counties along a 34-mile long study area from Union Station to the City of Santa Ana.  In addition to a No Build and Transportation Systems Management (TSM) alternative, the AA evaluated six build alternatives along various alignments: Bus Rapid Transit (BRT), Street Car, Light Rail Transit (LRT), Diesel Multiple Unit (DMU), High Speed Rail, and Magnetic Levitation Train.  SCAG completed the AA in February 2013 and recommended that further study be conducted on the following alternatives:

  • No Build
  • TSM
  • LRT along two alignments (West Bank Option 3 and East Bank)

The estimated Capital Cost for the Los Angeles County segment (in millions) was $1,984 - $2,231 (FY 2010 $)

Technical Refinement Study - Metro

Metro is currently conducting a Technical Refinement Study that builds upon the analysis from the SCAG AA, focusing on the Los Angeles County segment described above.  The Technical Refinement Study will update the travel demand modeling, update cost and ridership forecasting, and analyze challenges identified in the SCAG AA such as:

  • Investigating feasibility of Union Station access
  • Refining alignment and terminus station
  • Active railroad capacity
  • Constructing a new station on the Metro Green Line

The Technical Refinement Study is anticipated to be completed in Fall 2015.


There are no West Santa Ana Transit Corridor meetings scheduled at this time. Please check back for updates.
