Caltrain construction, maintenance Feb. 6-12

Written by 

Feb. 6-11, between the hours of 8 p.m. and 4 a.m. crews will be finishing up work on Caltrain's Grade Crossing Improvement Program. Work will take place at the following locations: in Burlingame at Oak Grove Avenue and Peninsula Avenue; in Redwood City at Main Street and Chestnut Street; in San Mateo at Villa Terrace Avenue and First Avenue; and in Menlo Park at Encinal Avenue, Glenwood Avenue, Oak Grove Avenue and Ravenswood Avenue

Throughout the project area, at least one lane of the impacted street will remain open. Flagmen will direct traffic and pedestrians around the construction.

Work on a $2.8-million project to add additional signals to the Caltrain signal system will take place in Belmont on Feb. 6-7 from 1 a.m. to 7 a.m.

Feb. 6-10, Caltrain will use a "detector" car to inspect the rails. This on-track car uses ultrasonic equipment to detect minute flaws in the rails that are not visible to the naked eye. These flaws may the result of manufacturing defects or simply develop over time. If a critical flaw is found, it is repaired immediately.

On Feb. 7, crews resurfaced the tracks between the Bayshore and Millbrae stations. Feb. 8-11, crews will replace ballast along the tracks between the Millbrae and Atherton stations.

On Feb. 12, work will be done on the tracks that cross Poplar Avenue bridge. The work is part of a project to replace the crossties on the tracks that cross four bridges in San Mateo. The work began on the northbound tracks that cross Tilton Avenue and proceed 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.

Feb. 8-12, utility poles located north of Bellevue Avenue in San Mateo and south of Churchill Avenue in Palo Alto will be replaced. On Feb. 7, crews replaced crossties on the tracks between the Atherton and Palo Alto stations and repaired and welded switches on the tracks near the San Jose Diridon station.
