Caltrain Construction and Maintenance: Sept. 14 to Sept. 20, 2013
September 12, 2013
San Bruno Grade Separation Project
Day work will be done from 7 a.m. to 6 p.m. This week, crews will continue painting the exterior, and working on the San Mateo and San Bruno bridge platforms.
Road work will continue this week with the street closure for San Bruno Avenue. Construction crews will continue excavating and removing portions of the roadway to lower streets and allow for greater vehicular clearance under the crossings. Once completed, the clearance for the intersection will be approximately 15 feet. The following is a list of road closure times and dates:
- San Bruno Avenue, between First and Huntington avenues, will be closed on two separate occasions. The first portion of the work will require partial closure of the street from 8 p.m. Friday, Sept. 13, until 5 a.m. Monday, Sept. 16. The second portion will shut down San Bruno Avenue at Huntington Avenue. That closure is scheduled for 8 p.m. Friday, Sept. 20, until 5 a.m. Monday, Sept. 30.
The $155 million project will elevate the Caltrain tracks above three existing at-grade street crossings at San Bruno, San Mateo and Angus avenues. A new elevated Caltrain station between San Bruno and San Mateo avenues will replace the station at Sylvan Avenue. Work on this project will not disrupt Caltrain service.

Communications Based Overlay Signal System (CBOSS) Positive Train Control (PTC) Project
The CBOSS PTC Project is an advanced signal system that will equip the corridor with federally-mandated safety technology and will increase system capacity to help accommodate future ridership demand.
The project will monitor and, if necessary, control train movement in the event of human error. This will increase safety by:
- Eliminating the risk of train-to-train collisions.
- Reducing risk of potential derailments by enforcing speed limits.
- Providing additional safety for railroad workers on the tracks.
- Improving grade crossing performance to reduce gate downtime and improve local traffic circulation.
The CBOSS PTC Project is also a key component of the Caltrain Modernization Program, which will electrify the Caltrain Corridor by 2019. An electrified Caltrain will be cleaner, quieter, and will upgrade the system to provide faster and/or more frequent service to more stations and more riders.
To implement the project, Caltrain will be identifying utilities, digging a small trench and/or boring close to the tracks to install a fiber optic cable. In order to maintain daytime train service, Caltrain will be performing some of this work at night.
