NS is on track with its PTC Implementation Plan to meet the 2018 and 2020 goals and was conditionally certified by the FRA in May 2017. PTC, or Positive Train Control, is technology designed to prevent train-to-train collisions, derailments caused by excessive speed, unauthorized incursions by trains into sections of track where repairs are being made, and movements of a train through an improperly aligned track switch.
The U.S. Congress has required that railroads install PTC on tracks that carry passenger trains or toxic-by-inhalation materials. The installation of PTC capability involves work on thousands of locomotives; a large new wireless communications network; and thousands of trackside devices connected to signals, switches, and other wayside devices.
Railroads have devoted enormous human and financial resources to develop a fully functioning PTC system.
»Several of the Norfolk Southern employees who have led the company’s efforts to develop and deploy the positive train control safety technology discuss the work and complexities involved in this video.
Here is a summary of Norfolk Southern’s progress through fourth-quarter 2017
The NS Engineering team has installed
- 3,437 radio towers
- 3,423 wayside interface units
- 120 switch position monitors
- 3,161 wayside radios
- 382 base station radios
The NS Mechanical team has installed and readied
- 2,354 locomotives with onboard computers
- 2,354 locomotives with PTC displays
- 2,269 locomotives with PTC-capable event recorders
- 2,354 locomotives with PTC-220 radios
We have 2,354 locomotives Fully-equipped and PTC Operable.
The NS Operations team is providing PTC training
NS has trained more than 18,315 employees and their supervisors, as required, on job-specific PTC material using hands-on, simulator, video, online, instructor-led and train-ride methods to deliver training.
Advanced Train Control, Information Technology and Operations teams have been testing our PTC system implementation for years.
- NS continued to verify and validate the PTC system in its Atlanta PTC lab with experts in the system and quality assurance. To date, we’ve tested over 12,917 scenario iterations of PTC states and functions and more than 132 iterations of software releases. Field acceptance testing occurs as new releases are ready for implementation.
- At the end of 4Q 2017, NS was operating PTC trains with NS transportation crews in revenue service across 3,387 miles of its PTC-required track.
NS also is working with 30 railroads to ensure our PTC operations will be interoperable.
