CONCORD, CA — Commuters faced new BART schedules today as the transit agency launched new systemwide changes.
The new timetable affects riders throughout Contra Costa County, who should not assume their trains will arrive at the usual time.
For Contra Costa County riders, the adjustments mean trains at Antioch, Pittsburg/Bay Point, Concord, Pleasant Hill/Contra Costa Centre, and Walnut Creek may no longer leave at the familiar times commuters have built into their routines.
BART warned riders that many familiar departure times have shifted by several minutes. The agency urged passengers to check the BART Trip Planner using travel dates of Aug. 10 or later.
The schedule represents a permanent timetable change, not a temporary service disruption.
BART said the new schedule is designed to reduce delays, improve transfers, and space trains more evenly.
One of the most noticeable changes affects the spacing between Yellow and Red Line trains.
BART previously scheduled the two lines with an uneven pattern that could put trains about five minutes apart, followed by a roughly 15-minute gap. The new schedule aims to space Yellow and Red Line trains about 10 minutes apart.
BART also redistributed Green and Blue Line trains. Those trains previously could arrive about three minutes apart, followed by a 17-minute gap. The new timetable generally spaces them eight to 12 minutes apart.
BART officials said the changes should create more consistent waits for passengers and reduce periods when several trains arrive close together before riders face a longer gap.
BART's newly posted Concord weekday schedule, for example, reflects the revised Yellow Line timetable for trains traveling toward Antioch and Pittsburg/Bay Point, as well as trains heading toward San Francisco International Airport.
BART traced the broader schedule overhaul to a bottleneck nearly 30 miles away from central Contra Costa County.
The agency changed train operations at Daly City Station after congestion there repeatedly created delays that spread to other parts of the BART system.
Trains that terminate at Daly City must leave passenger service and move toward the yard. BART said those train movements could interfere with trains continuing through the station, creating congestion that affected service elsewhere.
The new timetable also comes shortly before another service issue that will specifically affect Yellow Line passengers in Contra Costa County.
BART plans late-night single-tracking work Aug. 20 through Aug. 22 while crews perform rail work along the Yellow Line.
Passengers traveling through the affected area should expect delays of approximately 20 to 25 minutes during that work.
Even a shift of several minutes could mean the difference between boarding the usual train and watching it leave the platform.
