Positive Train Control

PTC will be installed on 100% of Union Pacific’s required rail lines and implemented on 75% of the required lines by the end of 2018.

Union Pacific has a comprehensive plan for positive train control (PTC) installation and implementation. By the end of 2018, PTC will be installed on 100% of Union Pacific’s required rail lines and implemented on 75% of the required lines.

When we filed our revised implementation plan in 2016, the goal was full PTC implementation on all required lines by the end of 2018. However, as we implemented this complex suite of technologies across our network, the largest one in the U.S., unanticipated operational issues developed.

These issues take many forms, all of which are magnified on an interconnected rail network. Unintended braking events, terminal dwell, and lower velocity collectively play a role in increasing variability. We are working diligently to resolve these issues, while maintaining the health, safety, resiliency, and fluidity of the rail network. We will continue our efforts to improve our operations and implement the remaining segments.

As permitted by Federal statute, Union Pacific intends to file with the Federal Railroad Administration an alternative schedule for implementing PTC on the remaining segments as soon as practicable, but no later than the end of 2020. We will meet all criteria necessary for an alternative schedule, including full network installation and implementation on the majority of required lines, by the end of 2018.

Union Pacific remains committed to PTC. The alternative schedule provides flexibility to problem solve issues that arise so that this critical safety system is implemented correctly. PTC will be installed and implemented for all passenger use on UP’s required lines by the end of 2018.
