Blue Line (BART)

The Blue Line is a rapid transit line in the Bay Area Rapid Transit (BART) system, serving the San Francisco Bay Area in California. It runs primarily in an east-west direction, connecting Dublin/Pleasanton in the East Bay to Downtown San Francisco and then southward to Daly City.

The Blue Line shares trackage with other BART lines along much of its route. Specifically, it shares track with the Dublin/Pleasanton–Daly City line for its entire length. It is known for providing direct service between the eastern suburbs and San Francisco, making it a popular route for commuters.

Service on the Blue Line typically operates from the early morning hours until late at night, with reduced service or alternative transportation options available during overnight periods. Passengers can transfer to other BART lines at various stations along the route, enabling connections to other destinations throughout the Bay Area. Schedules and real-time train information are available through BART's official website and mobile app.

The line has undergone modifications and improvements over the years to enhance reliability and capacity. These efforts include track upgrades, signaling improvements, and the introduction of new train cars. The Blue Line plays a vital role in the Bay Area's transportation network, providing a convenient and efficient mode of travel for residents and visitors alike.
