The CBOSS PTC Project is an advanced signal system that will equip the Caltrain 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.
Day work will occur June 30–July 3 from 7 a.m. to 5 p.m. to identify utility lines, pull inner-duct through existing conduit in the ground, and pull/test fiber optic cable. Crews will also install conduit on the Dumbarton Spur. Crews will work as quietly as possible.
Night work will occur June 29-July 3 from 8 p.m. to 6 a.m. Crews will be boring and/ or digging a small trench to install conduit for a fiber optic cable. Neighbors may experience some minor installation noise during this time and lights will be used in the area to help provide visibility. Crews will work as quietly as possible.
