Union Pacific's Positive Train Control Implementation Reaches New Milestones

Omaha, Neb., March 15, 2017

Union Pacific continues to make strides implementing positive train control, closing 2016 with several key milestones:

  • More than a quarter (26%) of track segments are PTC-ready. These 59 track segments, or subdivisions, are equipped with wayside devices (signals, switches and radios) and have defined GPS coordinates, which identify thousands of precise locations for systemwide PTC coordination. The PTC-ready segments cover a wide swath of UP's Western Region, from Southern California to Portland; from Portland to Pocatello, Idaho; and from Roseville, California, through Reno to Elko, Nevada.
  • Training efforts continue with more than 7,000 employees (18%) educated on PTC operations. Diverse training materials are tailored to a variety of employee roles, including engineer, conductor, dispatcher, maintenance of way/engineering, mechanical, signal, telecom and information technologies.

Additional progress includes:

  • 64% of required locomotives equipped with PTC technology.
  • 85% of required radio towers equipped with PTC technology.
  • 12% of the railroad's required route miles in PTC operation.
  • UP's PTC Safety Plan submission to the Federal Railroad Administration (FRA).
  • UP acquiring the necessary spectrum to support PTC operations.

February 2017 System Update

Developing and implementing a PTC system is a multi-dimensional process requiring a cross-functional, systemwide approach. Union Pacific's PTC system consists of multiple technologies functioning together to constantly monitor and manage train movements. These involve integrating signal and telecom elements; GPS; wayside, base station and locomotive radios; antennas and satellites – all to predict whether the train crew should be alerted to take action or if the technology should take control to slow or stop the train.

Through Dec. 31, 2016, Union Pacific:

  • Invested $2.3 billion in PTC. Union Pacific's current estimate for PTC's total cost is about $2.9 billion.
  • Installed 93 percent, or 16,008 miles, of total route miles with PTC signal hardware.
  • Partially installed PTC hardware on 93 percent of its 5,656 locomotives earmarked for the technology.
  • Equipped 2,441 locomotives with PTC hardware and software for revenue service demonstration (a test of the PTC system in a defined rail corridor).
  • Installed 93 percent of the wayside antennas needed to support PTC along the company's right of way.
