Downtown Extension Project - San Francisco, California

The Downtown Rail Extension (DTX) in San Francisco, Calif. will extend Caltrain commuter rail from its current terminus at Fourth and King streets to the new Transit Center. It will also deliver the California High-Speed Rail Authority’s future high-speed rail service to the Transit Center.

The San Francisco County Transportation Authority (SFCTA) assembled a team of experts, including SENER, to conduct a review of international mega rail project delivery best practices and assist in the review and evaluation of alternative governance and oversight arrangements for management and delivery of the 1.3-mile rail extension.

The effort consisted of research, expert interviews, a series of workshops with DTX stakeholders from the following agencies: Transbay Joint Powers Authority (TJPA), Caltrain, California High-Speed Rail Authority (CHSRA), San Francisco Mayor’s Office staff, San Francisco Planning Department, San Francisco Municipal Transportation Agency (SFMTA), Metropolitan Transportation Commission (MTC), Alameda-Contra Costa Transit District (AC Transit).

In addition, SENER performed the following important tasks:
  1. Reviewing and evaluating alternative governance and oversight possibilities for the management and delivery of the DTX.
  2. Evaluating and advising the Authority on DTX’s current funding plan, program delivery strategies and existing organizational structure within the TJPA.
  3. Advising the Authority of a recommended implementation approach, for the 2016 estimated $4 billion tunnel program, that could be implemented expeditiously and efficaciously.
  4. Recommending a DTX rail program delivery organization to advance the DTX program.
