On Sunday, Feb. 21, crews welded and repaired switches on the tracks in San Francisco and replaced switches on the tracks between the Broadway and Hayward Park stations. Feb. 21-25, crews will dump ballast along the tracks at various locations between the Millbrae and Sunnyvale stations. The ballast will be used for future maintenance projects.
On Feb. 26, work will be done on the tracks that cross Tilton Avenue. The work is part of a project to replace the crossties on the tracks that cross four bridges in San Mateo. Work will take place each week between the hours of 10 p.m. Friday and 8:30 a.m. Saturday. The work began on the northbound tracks that cross Tilton Avenue and proceeds south to Monte Diablo, Santa Inez and Poplar avenues, in that order. After work on the northbound tracks is complete, work will continue on the southbound tracks, beginning with Poplar Avenue. During the project, trains may operate on a single track at the Burlingame and San Mateo stations.
