The Transbay Transit Terminal’s last day of operation before demolition for the new and improved Transbay Terminal (scheduled to open August, 2017) was August 6, 2010. The new and improved Terminal will feature an underground train station for Caltrain and the future high speed rail system, a new bus terminal, stores, and a rooftop park. While the new terminal is constructed, temporary stops have been established in the immediate area for commuters.
Originally the terminal had been built for the electric commuter trains of the Southern Pacific, the Key System, and the Sacramento Northern railroads which ran on the south side of the lower deck of the Bay Bridge. The SP and Sacramento Northern trains ceased service across the Bay in 1941 and in 1958 the tracks were removed and replaced with pavement for bus use after the closure of the Key system.
