BART extension to San Jose on track, but new cars delayed - San Francisco Chronicle
Construction of BART’s next extension into Silicon Valley is on track to be completed by the end of the year, but the transit system may not have enough rail cars to fully serve the two new stations it will serve.

...
Meanwhile, work on the 10-mile, two-station extension from the newly opened Warm Springs/South Fremont station to the Berryessa neighborhood of San Jose is at least three months ahead of schedule. Work is 94 percent complete on the extension that was originally expected to open in spring 2018, said Stacey Hendler Ross, a spokeswoman for the Santa Clara Valley Transportation Authority.

Most of the article was about the difficulties with the new BART railcars, including the possibility that there may not be enough for the Berryessa extension when it opens.

Warning: BART tracks from San Jose to Fremont electrified -- the entire line.

No word on test trains running on it yet.

The Final Stretch - BART Silicon Valley Extension Phase I:
  1. Station Construction: Complete landscaping, station interiors and exteriors
  2. Static Testing: Perform all communications, track and signal tests
  3. Dynamic Testing: Test train movements along 10-mile extension
  4. Integration Testing: Integrate 10-mile extension with the existing BART system
  5. Safety Certification: Certify the safety and reliability of the integrated 10-mile extension
  6. Passenger Service!

Major Decisions about BART Silicon Valley Extension Phase II on the Horizon:
  • Single-bore vs. twin-bore tunneling
  • Station locations

Take a look at the new Milpitas BART station
The Berryessa extension is now set to open next summer.
Part of the adjustment in schedule stems from a change in how the new Warm Springs BART station operates. It needs to be converted from an end-of-line station to a pass-through operation.

BART spokesman Jim Allison said the trains need to be able to operate autonomously to maintain a schedule, and right now they’re set to start and stop their runs in Warm Springs.

“Adding 10 miles means the train control operations must be changed,” Allison said. “It involves verifying all the logic for the train controls.”
