- More capacity
- Redundancy to ensure a resilient city after a major quake
- Reduce dependency on automobile – more transit options
- Upgrade the First Transbay Tube
- Create more housing and jobs in existing city centers, and other neighborhoods
We are at a critical moment when BART is beginning studies for a new 2nd Transbay Tube, mayors of San Francisco and Oakland have publicly supported a new tube, and city staff in Alameda have voiced support. We cannot plan and fiddle around to build a 2nd Tube for 30 years. We need to develop a host of funding sources, plan the project and start building within seven years so a tube can be operational by 2026. I'll discuss funding, which is critical, later.
Most folks will want to see the rail options and maps now. I have outlined the reasons for a new Transbay Tube and rail lines after the maps.
Factors in deciding where a new Transbay Tube should go
- A High Speed Rail station in Oakland (in or near downtown)
- Rail lines that could interlink with BART's existing rail lines.
- Lines that pass through Downtown Oakland, Alameda, and sometimes Emeryville
The idea for a Third Transbay Tube comes from Roland Lebrun, who suggests that conventional rail should arrive in the former Oakland Army Base because rail from the San Francisco Transbay Center should leave via Howard Street in SF. To keep things simple, let's call this the Key Route alignment since this is where Key Route rail passed before the Bay Bridge was built.
