MOUNTAIN VIEW (CBS SF) — Caltrain added more train service to accommodate the throngs of fans leaving Beyonce’s Formation concert at Levi’s Stadium Saturday night.

Some 45,000 people are expected.

Concertgoers are encouraged to take Caltrain and VTA home to avoid stadium traffic headaches.

Caltrain will be running a special northbound train from the Mountain View station about 75 minutes after the concert is over.
