After initial data gathering, Link21 began development of potential train network improvements in early 2022 as part of Phase 1 activities. Current work is primarily focused on identifying and assessing concepts that include a new train crossing between Oakland and San Francisco, as well as service and infrastructure improvements for both BART and Regional Rail. Concepts were initially identified through data gathering, technical studies, a market analysis, and public and stakeholder input. Through ongoing stakeholder collaboration, as well as concept assessment, the Link21 Team is working to refine recommended improvements.
In early 2024, the Program hopes to go to the BART Board of Directors and Capitol Corridor Board of Directors with a recommendation of which train technology (BART or Regional Rail) will go in the crossing. Concept options that include station and service improvements, and infrastructure to support those improvements will continue to be assessed in 2024 and beyond as the Program works to identify a project to advance to Phase 2 Environmental Review.
Exploring the Possibilities
In fall 2022 and summer 2023, we shared six concepts:
- Four Regional Rail Concepts
- Two BART Concepts
We also assessed the potential of having both train technologies within a new crossing. Since that time, we have learned through further analysis that a single two-track crossing (one train technology) meets the travel demand to 2050 and beyond. Another two-track crossing with the other technology could still be built in the future.
Determining which train or vehicle technology goes in the crossing is an important step in identifying a future project to best achieve Link21 Goals and Objectives. We know that either train technology can serve the overall goals of the Program, but we are currently exploring different service and operational tradeoffs between train technologies and how they connect effectively to the larger network.
Concepts aim to provide riders with a variety of benefits such as:
- Connections to new communities and destinations
- Potential for fewer and more convenient transfers
- Improved travel time
- More reliable train travel between the Bay Area and the Megaregion
We are currently analyzing and refining these concepts to identify future solutions that take into consideration the region’s population, evolving workforce needs and travel patterns, air quality and climate change impacts, and more. We are committed to identifying innovative solutions for better connecting and building upon the existing train network and service for future generations. Wherever you wish to travel, Link21 is working to reach new communities, address unmet potential for transbay train travel, create better transportation solutions, and make riding the train a better, more equitable experience.
A Look at the Concepts
View some sample concepts under consideration below. Concepts demonstrate new tracks (thick lines) connecting to existing tracks (thin lines), transfer opportunities, new potential stations, and improved existing stations. Each concept allows for a variety of service improvements to transform future travel.
BART Train Technology in the Crossing
Concept A Regional Rail Salesforce Transit Center via Alameda
- Offers both Urban | Metro and Intercity | Express service on Regional Rail tracks
- Prioritizes an Oakland connection to BART over shorter travel time between communities along the Capitol Corridor route from the Sacramento Area to East Bay and Downtown San Francisco
- Creates new train connection in West Oakland (transfer between Regional Rail & multiple BART lines
- Provides new access to train service in Alameda
- Serves the Salesforce Transit Center, offering riders an easy trip to the Peninsula/Silicon Valley
