BART approves $798M contract for new train control system

The Bay Area Rapid Transit’s (BART) board voted to award a $798 million contract to Hitachi Rail STS USA Inc. to design and build a modern Communications Based Train Control (CBTC) system that will dramatically improve future BART service.

Replacing the current train control system, which is 47 years old, will allow BART to run more trains closer together and significantly enhance Transbay capacity. The contract is expected to be the largest BART award this decade.

“This will be a pivotal project in BART’s history,” said BART GM Bob Powers. “We will now be able to eliminate aged and obsolete equipment. Modernizing our train control system will help us to support future ridership in the busiest sections of our system.”

Funding for the new train control system is coming from a variety of local, state, and federal sources including $400 million from Measure RR. Voters in Alameda, Contra Costa, and San Francisco counties approved Measure RR in 2016 to provide $3.5 billion in bond funding to rebuild BART’s infrastructure. Major funding is also anticipated to come from the Federal Transit Administration’s Capital Investment Grant Program.

The new train control system is one of BART’s Big Four Capital Projects that comprise the Transbay Corridor Core Capacity Project. The $3.5 billion project calls for a new train control system, 306 more Fleet of the Future cars, a maintenance complex for the new train cars, and new electrical substations to ensure reliable power for all trains.

BART currently relies on a fixed-block train control system. The technology is very safe but relies on widely spaced signal blocks to denote train occupancy, contributing to longer distances between trains and increased travel times, according to the agency. The new CBTC system can more precisely detect a train’s location, which improves reliability and allows for more efficient train movement. Shortening the distance between trains means BART can operate more trains and decrease travel times. The new train control system will be installed over the next 11 years.

In addition to the main contract, Hitachi Rail has been awarded nearly $82 million in contracts to design, build, and support the CBTC system for the Silicon Valley Extension. Funding for this work will be provided by the Santa Clara Valley Transportation Authority.
