The Santa Clara Valley Transportation Authority is one step closer to bringing BART service to San Jose.
VTA announced this week testing has started with trains on the BART Silicon Valley Berryessa Extension -- about 10 miles that stretches from Fremont to San Jose.
During the testing, officials said train movements will be slow at first and will eventually build up speed to simulate BART service up to 80 mph.
VTA officials said testing will occur in two shifts: 7:30 a.m. to 5:30 p.m. and 5:30 p.m. to 3:30 a.m. Testing will be held every day except Sunday.
Estimates show BART will take as many as 20,000 commuters off roadways between the new Warm Springs station in Fremont and the Milpitas station and another 20,000 between the Milpitas and Berryessa stations.
