In 2008, Congress required railroads install positive train control(PTC) on mainlines that transport any poisonous-inhalation-hazardous(PIH) materials and where regularly scheduled intercity passenger or commuter rail services are provided. PTC uses communication-based/processor-based train control technology that provides a system capable of reliably and functionally preventing train-to-train collisions, overspeed derailments, incursions into established work zone limits, and the movement of a train through a main line switch in the improper position. 2, record 1, English, - positive%20train%20control
