| Description | The project implements positive train control (PTC) technology and associated supporting infrastructure required to comply with federally-mandated PTC requirements (49 CFR 236, Subpart I). The project will be applied to the full MBTA commuter rail system covering approximately 400 combined track miles (purple lines on the map). It consists of the installation of onboard controls, wayside signals, system-wide communications, and an upgraded, centralized dispatch. The project provides significant safety benefits by addressing the impacts of human error to automatically reduce train speeds or stop trains to avoid a collision or derailment. The system can prevent trains from traveling at excessive speed through or entering work zones without proper authority, keep trains from being routed though misaligned switches, and protect the movement of trains through failed or inoperative grade-crossing systems. The interoperable system accommodates tenant and host railroads sharing tracks. |
