Positive Train Control

The Illinois Department of Transportation (IDOT) is working with Union Pacific Railroad and Amtrak as they install and test Positive Train Control (PTC) and enhanced grade crossing warning system along the corridor. PTC is a safety system that communicates conditions at the crossings to the approaching trains, which could allow the train engineer to react and reduce speeds in the event a warning system has malfunctioned or if a vehicle is detected on the tracks. Before trains can operate at speeds greater than 79 miles per hour (mph), the PTC system at grade crossing locations and within the train must be tested for efficiency and compliance with Federal regulations. Once PTC testing is complete and approved, trains will begin operating at speeds of up to 90 mph. This initial increase in speeds is anticipated to begin in the first half of 2021. The overall Project encompasses improvements designed to accommodate the operation of higher speed passenger trains, up to 110 mph.
