The San Mateo County Transit District (SamTrans) will host a virtual public meeting to discuss the Dumbarton Rail Corridor project on Monday, March 15, starting at 6 p.m.
The project envisions creating an approximately 18-mile route between Redwood City and Union City for a new transit system that would connect Caltrain to BART. Transit stops would be located in Menlo Park, East Palo Alto, Newark, Fremont and Union City. An estimated 24,000 riders could use the system every day, according to a February 2020 projection by SamTrans.
The Dumbarton Rail Corridor effort kicked off in 2018, when SamTrans entered into an agreement with Facebook and the Plenary Group, a public infrastructure investor and developer. Their partnership, called Cross Bay Transit Partners, was formed to facilitate the necessary state and federal environmental impact analyses, as well as a fiscal impact analysis, to determine if it would be feasible to rebuild the defunct transbay rail line for the new cross-bay route.
Although Facebook announced last May that it was reconsidering its commitment to pay for the analyses, citing the need to redirect its resources because of the pandemic, it later clarified that it would remain in the partnership until the pre-environmental analysis work was completed.
That early phase is currently underway with the development of conceptual alternatives. The partnership hopes to finalize the alternatives this spring.
Monday’s community meeting will take public input on two potential routes and four transportation options: commuter rail transit, light rail transit, bus rapid transit and autonomous vehicle transit. Commuter rail typically operates on traditional train tracks, while light rail generally requires its own track system with overhead electricity lines. Autonomous vehicle transit is an emerging technology that uses independently operating pods to transport small groups of riders.
The end goal of the project is to provide crossbay transit service that could connect Caltrain to ACE, BART, Capitol Corridor and, eventually, California High Speed Rail, the project website states.
Funding for the potentially $3 billion project remains a bit of an unknown, although transit leaders say that the project is eligible for public funding under the recently passed Regional Measure 3 (bridge toll tax) and San Mateo County’s Measure W, as well as Federal Transportation Administration Capital Investment Grants and other US Department of Transportation programs.
The original Dumbarton rail bridge opened in 1910 but fell into disrepair and was heavily damaged in a fire in 1998. SamTrans bought the rail right-of-way in 1994 but hasn’t had funds to redevelop it, though several studies on potential rail projects have been completed over the years. The current Dumbarton road bridge lies to the north of the rail bridge and, before the pandemic, was routinely clogged with commuting drivers during weekday rush hours.
Local transportation leaders have said that the Dumbarton Rail Corridor project could significantly relieve that traffic congestion by providing a much-needed commute alternative.

From the Dumbarton Corridor FAQ:
“What is the anticipated timeline for the project? Following the completion of the Alternative Analysis in Spring 2021, the District, in partnership with MTC, will evaluate the timing of appropriate next steps. The project is part of Plan Bay Area 2050 to be completed approximately by 2036.”
This may take a while, folks.
I researched a re-build of the Dumbarton Trestle over 10 years ago when the topic came up before the Menlo Park City Council. I discovered studies wherein divers had analyzed the foundations and found them (concrete and rebar) deteriorated beyond repair. Even then, the projected costs of refurbishing this trestle were staggering. Current seismic safety standards will demand a safe, secure and reliable track system that did not previously exist.
Here’s a clue to possible future trestle cost estimates: The 2008 California high-speed rail bond issue (Prop. 1A) promised a train system costing $33 billion. Today the cost forecast is $100 billion and they’ve merely started construction, and are again raising cost estimates dramatically. In the US, such cost inflation has become standard for very large infrastructure projects. (See: Boston Big Dig, for further examples.)
At the time of this prior Dumbarton trestle interest, the US Coast Guard also had a concern, seeking removal of the entire structure. Any rebuild will have to take South Bay ship navigation interests into account.
I certainly hope that all the interested parties do their due diligence before coming to us taxpayers asking for a blank check.

When have they EVER done that? They’ll just lie their asses off like they did with HSR to get the uninformed, sucker voters to vote for it then the cost will go through the roof and the taxpayers will be stuck paying for another boondoggle.
