METRA TO INSTALL POSITIVE TRAIN CONTROL
March 22, 2010, by Jeffrey J. Kroll
Metra plans to spend $100 million to install a high-tech system called positive train control (PTC) before 2015. PTC is a complex system of GPS systems, computers and other equipment that takes over the train in the event that it approaches another train. The system could override an engineer who may be distracted or otherwise miss or ignore a warning signal to slow down.
