This week, U.S. Transportation Secretary Ray LaHood and Federal Railroad Administrator Joseph Szabo announced safety regulations requiring Positive Train Control (PTC) technology to be installed on major rail lines around the nation, as well as commuter and intercity passenger rail routes.
Train control systems such as PTC are now mandatory for most passenger rail operations and for trains hauling certain hazardous materials, but are not required for closed passenger rail systems such as light rail, rapid transit and subways.
