BART Board Selects Warm Springs / South Fremont Station As Name For New Station
The BART Board of Directors voted to officially name the new station constructed by the BART Warm Springs Extension the Warm Springs / South Fremont Station. Read more about the BART Board's decision.
The Warm Springs Extension will add 5.4-miles of new tracks from the existing Fremont Station south to a new station in the Warm Springs District of the City of Fremont, with an optional station to be located approximately midway, in the Irvington District. The optional Irvington Station is dependent upon future funding through the City of Fremont and may be added at a later date. For more information on the Irvington Station, visit the City of Fremont website at http://www.fremont.gov.
The project alignment will cross over Walnut Avenue; under Stevenson Boulevard, Fremont Central Park and the Union Pacific Railroad track in a subway; over Paseo Padre Parkway; under Washington Boulevard; under Auto Mall Parkway; and over South Grimmer Boulevard.

The Warm Springs / South Fremont Station will feature an at-grade island platform with an overhead concourse, intermodal access to Valley Transit Authority (VTA) and Alameda-Contra Costa Transit (AC Transit) buses, as well as taxi and "kiss and ride" passenger drop off areas, all via Warm Springs Boulevard. The new station will also provide approximately 2,000 parking spaces. Get the Warm Springs / South Fremont Station Conceptual Design.
As with all BART stations, the Warm Springs / South Fremont Station will be fully accessible to pedestrians and bicyclists, and will include bike lockers, elevators and escalators, Braille signs and a tactile sight path to aid riders with disabilities.
In keeping with the Federal Transit Administration (FTA) guidelines to incorporate art into mass transit projects, BART has commissioned artwork from professional artists for the new Warm Springs / South Fremont Station and for the concrete seating areas at the existing Fremont Station. Learn more about the Warm Springs Art Program.
In 1992 the BART Board of Directors certified the Final Environmental Impact Report (EIR) and adopted the extension; however, the project was not constructed because sufficient funds were not available. In 2006 the project completed an environmental review under the National Environmental Policy Act (NEPA). This was in addition to the California Environmental Quality Act (CEQA) clearance that was completed in 2003. Read the history of the Warm Springs Extension environmental process and a chronology of the Warm Springs Extension project.
In 2007 BART devised an implementation strategy whereby the project would be constructed via two large contracts: The Fremont Central Park Subway Contract and the Line, Track, Station and Systems Contract. This approach is intended to minimize overall escalation costs and most appropriately deal with the special needs associated with the underground portion of the project in Fremont Central Park.
Fremont Central Park Subway Contract
The Fremont Central Park Subway Contract (Subway) includes a mile-long subway beneath Fremont Central Park, an embankment for the BART trackway, two ventilation structures and relocation of recreational facilities within Fremont Central Park. The contract work area extends from just south of Walnut Avenue, through Stevenson Boulevard and Fremont Central Park, including a portion of Lake Elizabeth, and to the east side of the Union Pacific Railroad (UPRR) freight tracks just north of Paseo Padre Parkway. The BART Board awarded the Subway Contract to the Shimmick/Skanska Joint Venture on May 28, 2009 for the low bid of $137 million and the contract was completed on schedule.
Line, Track, Station and Systems Contract
Warm Springs / South Fremont Station Rendering
The Line, Track, Station and Systems (LTSS) Contract is a design-build contract intended to perform the final design as well as construct the remaining parts of the Warm Springs Extension, including the trackway, systems, tie-in at the Fremont Station, and the new Warm Springs / South Fremont Station and parking lot. This contract will also include certain provisions to facilitate both the further extension of BART into Santa Clara County (by VTA), and the possible future construction of an intermediate station in the Irvington District (subject to funding by the City of Fremont).
The Warm Springs / South Fremont Station, including the surrounding site, is being carefully designed to promote both multi-modal and disabled access as well as to accommodate potential future transit oriented development. The station will meet not only BART's Facility Design Standards, but also the expectations of the BART Bicycle Task Force, the BART Disability Task Force, and the accessibility requirements of the State Architect. Furthermore, the site development will be well integrated within the surrounding infrastructure, both existing and planned. The conceptual and preliminary design of the station itself has been the work of Robin Chiang & Company of San Francisco, architectural sub-consultant of BART's General Engineering Consultant, Parsons Brinckerhoff, Inc. The open and gracefully geometric design, coupled with ample landscaping and a public art component, is intended to capture both the spirit and energy of BART, as well as the history and culture of the Warm Springs District of Fremont. This design concept will now be completed and detailed by the Design-Build contractor's architect, HNTB, as part of the execution of the LTSS contract.
Tail Track Building Demolition Contract
This contract removed or modified various existing structures along Warm Springs Court in preparation for construction of the BART trackway south of the Warm Springs / South Fremont Station. In October 2011, the contract was awarded to Parc Services of Livermore, CA, for $1.06 million. The contract was completed on schedule in October 2012.
Solar Power at the Warm Springs / South Fremont Station
|Warm Springs / South Fremont Station Solar Panels|
The Warm Springs / South Fremont Station has nearly 2,000 solar panels installed on the station roof and on parking lot canopies. These were installed and will operate for at least the next 20 years under a “power purchase agreement” between BART and SolarCity. The panels went into operation on September 29, 2016 and have the capacity to generate 512 kilowatts (kW) of power, which is more than enough to serve all the daytime electricity needs for the Warm Springs / South Fremont Station. For comparison, the average California home with rooftop solar has about 5 kW of capacity.
Partners and Funding
The total project budget for the Warm Springs Extension is approximately $890 million. The various funding partners and their share in the total project are as follows:
- $215 million Alameda County Transportation Improvement Authority (ACTIA), Measure B Tier 1
- $100 million State of California Traffic Congestion Relief Program
- $176 million Metropolitan Transportation Commission (MTC) Regional Measure 2 Bridge Tolls
- $118 million MTC Regional Measure 1 Bridge Tolls
- $69 million State of California Transportation Improvement Program (STIP)
- $2 million Alameda County Congestion Management Agency (CMA)
- $40 million MTC Proposition 1B - 50% BART (Revenue Based), 50% MTC (Population Based)
- $92 million MTC Proposition 1B State & Local Partnership Program (SLPP)
- $24 million BART Agency Contribution
- $54 million San Francisco International Airport (SFO) Extension Surplus Revenue
Sufficient funding for all project construction has been secured.
Warm Springs Extension Construction Schedule
Major construction on the Warm Springs Extension began in August of 2009 with the commencement of the Fremont Central Park Subway Contract. The Subway Contract was completed in April 2013. Major construction of the design-build Line, Track, Station and Systems (LTSS) contract, which began in October of 2011, was completed in the summer of 2016. The Warm Springs Extension opened for revenue (passenger) service on March 25, 2017, following a period of rigorous testing and CPUC approval.

Washington Boulevard and Paseo Padre Parkway Railroad Grade Separation Project – Update
In May 2010 the City of Fremont completed the Washington Boulevard and Paseo Padre Parkway Railroad Grade Separation Project. The grade separation at Paseo Padre Parkway included an overpass for future BART trains, and was constructed by the City of Fremont via an agreement with BART to avoid future disruption during construction of the Warm Springs Extension. The Grade Separation project eliminated six railroad grade crossings, relocated interfering utilities and made the railroad corridor to the southeast of Fremont Central Park compatible with the WSX project alignment.
Silicon Valley Rapid Transit Corridor Project
