BART Warm Springs Extension Project is Working through Final Testing

is expected to begin Winter 2017

The BART Warm Springs Extension is clearing final hurdles of the project. Since the beginning of the project, BART’s project team has endeavored to balance the need to complete the work on time, on budget and to meet design specifications, function and quality, while maintaining project safety standards and minimizing construction impacts to the community. 

Passenger safety, system reliability and full operational readiness are the top priorities as BART prepares the new line for service.

A Little History is in Order…

Phase 1 of the Project – the one-mile subway built beneath Fremont Central Park and the eastern lobe of Lake Elizabeth, began in 2009 and was completed on schedule and under budget, early in 2013.

Phase 2 of the Project – the final design and construction of the remaining line, track, station and systems, was originally scheduled to begin in 2010 and to be completed in 2014.  However, due to funding delays, the start of Phase 2 was postponed to 2011 and its scheduled completion was pushed back to late 2015.

The Systems Work – this work is included in the Phase 2 “Design-Build” contract, and is a mix of specialized technical work ranging from: automatic train control, traction power, communications, automatic fare collection and other technical elements. This component, which represents BART’s first fully digitized system to be fully integrated into BART’s 40-plus year old system, adds an extra dimension of complexity to this extension project.

Unique Factors Create Challenges to the Timeline – Earlier this year, project testing was repeatedly interrupted by unanticipated faulting within the aging high voltage, 34.5kv power supply cables, needed for providing a reliable power source for the extension.  The 45-year-old cables were successfully decommissioned and replaced this summer by BART Maintenance and Engineering personnel – clearing the way for the project to continue with its rigorous testing program.

Where Are We Now?  BART is working through Automatic Train Control issues identified with our contractor that is requiring software modifications and additional testing.  Upon the conclusion of verification testing, a 3 to 4-week period of final preparations called “Pre-revenue Operations” will begin.  Once we reach this final phase and are able to guarantee safe and reliable service, a date for start of passenger service will be announced.

We sincerely apologize for the delay and thank our customers for their continued patience.

On Saturday, August 1 and Sunday, August 2, 2015, BART representatives partnered with the City of Fremont in a joint booth celebrating the annual Fremont Festival of the Arts event.  Director Blalock was on hand both days to greet the community and help answer questions regarding BART and the Warm Springs  Extension (WSX) Project. The Director was joined by WSX Project Manager Paul Medved and his project management team along with representatives from BART Police. BART was able to directly engage with more than 1,500 people over the 2-days, ranging from deep conversations about the WSX project to “selfies” taken with the BART mobile. Visitors were pleasantly surprised by the progress to date. The BART Mobile was a “big hit” and a significant draw to our joint booth along with large size visuals, and informative and fun marketing materials. Thanks to the City of Fremont, students from Irvington High School dedicated their community service hours to support the joint booth.

BART Warm Springs Extension Ground Breaking: The Way to San Jose

On Wednesday, September 30, 2009, over 200 people gathered in Fremont Central Park to celebrate the formal ground breaking for the BART Warm Springs Extension Fremont Central Park Subway Construction. “We have found the way to San Jose,” remarked Scott Haggerty, Chair, Metropolitan Transportation Commission and Supervisor District One, Alameda County Board of Supervisors.

The ground breaking ceremony, complete with music provided by the California School for the Blind Jazz Ensemble, included remarks from representatives of organizations from both Alameda and Santa Clara Counties. “This is not just a Fremont project, but a project for the entire region,” commented BART Board of Directors President Thomas Blalock. Other agencies represented included the City of Fremont, the California Senate, the California Transportation Commission, the Silicon Valley Leadership Group, the Alameda County Congestion Management Agency, the Alameda County Transportation Improvement Authority, the City of Union City, Caltrans, Santa Clara Valley Transportation Authority, and the Metropolitan Transportation Commission.

Lauded as the gateway to Santa Clara County, the $140 million Subway Contract will construct a mile-long subway for BART tracks from just north of Stevenson Boulevard, under Fremont Central Park, Lake Elizabeth and the Union Pacific rail road tracks to just south east of the park. The contract will also build a new dog park, basketball complex, and parking lot to replace facilities that will been removed next year to make way for construction of the subway. The project will also construct embankment between Walnut Avenue and Stevenson Boulevard for future trackway that will connect the Warm Springs Extension to the Fremont Station.

The subway construction is expected to conclude in 2013. Work on the Design-Build Line, Track, Station and Systems (LTSS) contract is targeted to begin in the fall of 2011, with revenue service to Warm Springs anticipated late 2015.
