Beginning this summer, the BNSF Line between Aurora and Chicago’s Union Station, which serves residents at the Lisle Metra stop, will be the first to implement the new Positive Train Control (PTC) safety system. This system will provide extended safety measures for train riders and will have an impact on train schedules.

PTC is a federally-mandated safety system that provides different safety functions, including stopping trains automatically if the engineer fails to obey a signal, or if the speed limit is exceeded. The safety system integrates GPS, trackside sensors, communications units and other navigation systems on trains. All of these components track trains and monitor the crew’s overall compliance with safety regulations.

While this system cannot prevent all accidents, it does increase safety by preventing train-to-train collisions, unauthorized entry into works zones, and derailments due to speeding or moving through misaligned track switches.

Changes will be made to Metra schedules to accommodate the implementation of the PTC safety system and will relieve overcrowding on some of the busiest trains, match schedules to actual operating conditions, and reduce congestion. These changes will result in changes to the total running times and the station stop patterns for all trains on the BNSF line.  While this enhancement will require a revision of the line’s current schedule, there are no planned changes to the weekend train schedule.

The proposed weekday schedule revision is now available at and can be found by selecting ‘Proposed BNSF Schedule Changes due to Positive Train Control’ on the website’s homepage.

Please take a few minutes to watch these two very informative videos we’ve posted on YouTube about Positive Train Control (PTC). You’ll have a better understanding of PTC and the complexity of implementing and operating the system.

The new schedule is proposed to be implemented in June or July of 2018. Further explanation about how and why PTC will impact schedules can be found by viewing a video, here:
