The BART Train Control Modernization Program (TCMP) is a $1.14 billion investment to replace the existing train control system with a new communication-based train control (CBTC) system and associated train control power cables and interlock cables, allowing BART to achieve the shorter headways needed to operate 30 regularly scheduled trains per hour on the trunk line between Daly City and the Oakland Wye. The newcommunications-based train control system will be based on a moving block signaling approach throughout the existing system and will be installed within or adjacent to the existing BART trackway and wayside facilities. New zone controllers, interlocking controllers and wayside radio transponder tags will be installed throughout the trackside alignment, train control rooms and central control facilities.
Cars and maintenance vehicles will be outfitted with processor-based controllers, transponders, communication equipment and location sensors. To achieve the shorter headways needed to operate 30 peak hour trains per hour through the Transbay Tube, BART will replace its existing fixed-block train control systems with a new, industry-proven, Communications Based Train Control System (CBTC).
BART has developed a multi-phase implementation program that will begin by testing CBTC equipment on BART’s existing test
track in Hayward, and then once the CBTC equipment has been sufficiently proven on test tracks, BART will implement CBTC along the mainline tracks in stages. The scope of the CBTC project includes installation of lineside equipment within BART’s existing right-of-way throughout the entire system. CBTC allows trains to safely operate closer together than the current fixedblock train control system, thus increasing throughput and capacity. CBTC has been implemented on many of the busiest rail systems in Europe and Asia, and is now the worldwide standard for high-capacity transit train control. SSC is the Resident Engineer responsible for delivering the $60+ million dollar enabling works project which includes removal and replacement of existing train control and electrical equipment along the BART legacy system. This work includes, but is not limited to:
• Procurement and installation of twenty-three (23) new Switch Machine Power Supply and Control (SPSC) Termination Cabinets
• Procurement and Installation of twenty (20) new Cable Entrance Cabinets
• Modification to nineteen (19) existing Cable Entrance Cabinets
• Modifications to thirty-nine (39) existing switchboards and thirty-eight (38) existing 33-1A panelboards including installation of
new Circuit Breakers
• Procurement and installation of related raceways, junction boxes, cabling and grounding.
• Civil and structural works related to raceway and foundation installation
• Select demolition and removal off-site of decommissioned equipment.
SSC’s various Construction Manager (CM) roles for the project are as follows: pre-construction activities, contract administration,
quality assurance, schedule management, change management and claims mitigation, submittal and RFI review, and subject-matter expertise.
