Sonoma-Marin Area Rail Transit (SMART) is a new start passenger train rail system located in San Francisco’s North Bay. The length of the initial operating segment is 38 miles and will run from downtown San Rafael to just north of Santa Rosa.
MRS has turnkey responsibility to design, furnish and install the train control and communications systems.
The train control system includes 24 control points, 29 new crossing warning systems, 17 onboard train control sets and the upgrade of 34 existing crossing warning systems. The system is an enhanced Cab Signal System, upgraded to provide functionality required by the Positive Train Control (PTC) aspects of the Rail Safety Improvement Act of 2008.
A fully functional voice and data communication system using a fiber optic backbone will run the entire length of the line, and a dispatch operations control center will be installed at the SMART Operations and Maintenance Facility in Santa Rosa. The systems scope of work includes work at a moveable bridge that spans the Petaluma River. The system will support operations of both commuter and freight trains.
MRS completed all grade crossing and wayside signal installations in late 2015. Integration testing began January 2016 with completion in April. Crossing and ATC static and dynamic integration testing wrapped up in May. PTC installation and static testing is finished and dynamic testing is set to start late this summer. Radio equipment testing is ongoing and will complete this summer. Pre-revenue on-track testing is slated for this fall, followed by revenue service later in 2016.
