Beginning Monday, June 16, Caltrain will suspend electric train service for about 8 months between San Jose Diridon and Tamien stations to replace a rail bridge over the Guadalupe River. During this time, a free bus bridge will be available between San Jose Diridon and Tamien. Diesel train service to and from Gilroy will remain unaffected, with these trains stopping at Tamien Station during weekday commute hours.

Caltrain will replace one of the bridges spanning the Guadalupe Creek, originally constructed in 1935. Due to its location over a waterway, the project required complex coordination with various governmental agencies and must be completed during the summer dry season. Caltrain built an adjacent concrete bridge in 1992 and recently finished lengthening it before starting the electric train service as part of the replacement project.
