Things To Know: Grade Separation Update

Construction, Installation and Maintenance: Jan. 18 to Jan. 24, 2014

Construction

San Bruno Grade Separation Project

Find out what's happening in San Brunowith free, real-time updates from Patch.

Day work will be performed from 7 a.m. to 6 p.m. This week, crews will continue work at the San Mateo and San Bruno bridges, ramps, stairwells, walls and elevators. Crews will also be working on the sidewalks at San Mateo and San Bruno avenues that will require a temporary closure. Pedestrian detour signs will be posted around the impacted area.

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.

Installation

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 and the trains 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, at various locations, 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.

For more information, please call the dedicated outreach line at 650.508.6499; visit the website at www.caltrain.com/CBOSSPTC or email caltrainptc@samtrans.com.

Maintenance

Caltrain will perform routine maintenance at several locations next week. To avoid disruptions to service, the work will mainly take place Saturday through Friday from 8 p.m. to 6 a.m. There will be some construction noise but crews will work as quietly as possible.

San Francisco to San Jose
Saturday, Jan. 18, to Friday, Jan. 24, crews will power wash and perform janitorial work at Caltrain stations between the San Francisco and Tamien stations. Also, Saturday, Jan. 18, and Sunday, Jan. 19, crews will use a Sperry detector car to check the rail for flaws or defects.
