Work will continue on the new pedestrian underpass at the Santa Clara station. The underpass will connect the north- and southbound platforms, allowing two trains to pass through the station at the same time and improving safety for pedestrians in the station. Passengers at the station are boarding the train from a temporary platform. Passengers are asked to observe all posted signs and follow direction from identified ambassadors in the station. The temporary platform will be in use for approximately six months.

Scheduled train stops at the station will not be affected by the construction. Tickets can still be purchased at the existing ticket vending machines.

The work is part of an 18-month station improvement project that will add a new wider, longer center-boarding platform and extend the southern platform 150 feet.

Work continues on a VTA project that will improve safety at eight grade crossings in Sunnyvale, Mountain View and Palo Alto. Oct. 31 to Thursday, Nov. 4 between the hours of 8 p.m. and 4 a.m., crews will work at Mary Avenue crossing in Sunnyvale and at the Castro Street crossing in Mountain View.

On Oct. 31, crews welded the tracks in the San Francisco train yard. Oct. 31 to Nov. 3, Caltrain will use a sophisticated on-track vehicle to inspect and record the condition of the tracks. On Oct. 31, crews replaced crossties and resurfaced the tracks between the Sunnyvale and Santa Clara stations.

Nov. 1-4, crews will replace crossties and do routine maintenance on the tracks between the Millbrae and Atherton stations. Nov. 1-3, crews will be working on signal house wiring modifications between the San Jose Diridon and Tamien stations. Oct.  29-30, new rail was installed on the tracks near the Tamien station.
