Class I Railroad PTC Upgrade

Class I Railroad PTC Upgrade


Project Challenge

The U.S. Rail Safety Improvement Act of 2008 requires Positive Train Control (PTC) to be installed by 2015 on rail routes that carry passengers or hazardous materials. A PTC system allows for automatic braking in the event of human error, reducing the potential for train accidents. Rani Engineering is providing the railroad signal engineering for a subdivision being upgraded for PTC. The project is the railroad’s largest PTC upgrade to date.

Rani Engineering Solution

  • Designing upgraded and new control points, interlockings, intermediate signals, electric locks, and handthrow switches to function with PTC and to meet current FRA requirements
  • Creating current track profiles and construction overviews to reflect existing equipment and proposed construction within the subdivision
  • Upgrading and replacing at-grade crossing equipment, including GE and Safetran (Invensys Rail) equipment
  • Lengthening crossing approaches and creating/updating crossing disable procedures to meet current standards
  • Reviewing existing and proposed software and construction plans to create up-to-date aspect charts for the project
  • Creating PTC mapping of locations
  • Finding and recommending cost-effective design modifications
