Project Description: 

The Project is the implementation of positive train control technology and associated supporting infrastructure required to comply with the federally-mandated PTC requirements (49 CFR 236, Subpart I).  The Project will be applied to all of MBTA’s commuter rail system with approximately 400 combined track miles (purple line on the map).  The Project provides significant safety benefits, by preventing trains from incursion into work zones without proper authority, keeping trains from being routed though misaligned switches, and protecting the movement of trains through failed or inoperative grade crossing systems.  It will be interoperable to accommodate tenant and host railroads sharing tracks. 

The Project is included in both state and local transportation planning documents, indicating that the Project is a high priority at the state and local levels.
