From south to north, the Blue line starts at Santa Teresa station in South San Jose, then shortly enters the median of State Route 85 until the interchange with State Route 87, where it exits the median and makes a sharp turn to serve Ohlone/Chynoweth station.[1] The first section of the Guadalupe line opened on December 11, 1987,[4] with 7.4 miles (11.9 km) of track allowing trains to operate between Old Ironsides station, located near the California's Great America theme park, and a temporary Civic Center 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 fourth and final section of the Guadalupe line opened the following year on April 25, 1991,[4] with 9.7 miles (15.6 km) of track, continuing down the median of State Route 87 until it approaches the interchange State Route 85, where the tracks briefly exit the median to serve Ohlone/Chynoweth station.On October 4, 2010, the VTA introduced a Commuter Express light rail service on this line, which operated between Baypointe and Santa Teresa stations.[6] It offered free WiFi access on all trains on this service,[7] and promised time savings of six to eight minutes.
