On Friday, May 7, a geometry car will operate on the Caltrain tracks between San Francisco and San Jose. This on-track vehicle outfitted with a sophisticated computer system is used twice a year to measure and record the alignment of the tracks.
On May 14, Caltrain will use an on-track truck to spray weed killer along the right of way. Weed abatement is necessary to prevent brush fires on and around the train tracks.
May 9-13, crews will replace crossties, weld and resurface the tracks between the Bayshore and San Mateo stations. May 9, crews will weld on the tracks between the Sunnyvale and San Jose Diridon stations.
