The first section of the Guadalupe line opened on December 11, 1987, with 7.4 miles of track allowing trains to operate between Old Ironsides station, located near the California's Great America theme park, and a temporary station at First and Younger, near the junction of the branch running west on Younger to VTA's Guadalupe Division, the maintenance and storage yard for trains. The section of track between Old Ironsides station and Tasman station is no longer served by Blue Line trains, but is still used by the Green Line.
