This year, as in the last two years, the San Jose Grand Prix race track will cross the light rail tracks in Downtown San Jose. The light rail system will be split apart during the Grand Prix.
Unlike last year when the light rail system was split in four ways during the racing weekend. VTA would be splitting the system in three ways: lines from Mountain View and Alum Rock would continue to Downtown San Jose. The line from Winchester will continue to Santa Teresa at the Children's Discovery Museum.
The line from Winchester to Santa Teresa, although it will be much more user friendly, does present some operational challenges. The stations between Race and Winchester can only accomodate two car trains, whereas other stations can accomodate three car trains. Also, the Winchester line has two single track segments, which limits train frequency. It is possible that VTA would operate some trains from Santa Teresa only to San Jose Diridon Station.
