CN boosts rail, wheel flaw detection efforts

Written by 

CN has announced a program to acquire additional monitoring equipment to enhance its strong technological base for early detection of defects.

Said CN Executive Vice President and Chief Operating Officer Jim Vena, "We're stepping up our inspection and detection capabilities. We've had a major push in recent years to increase the number and quality of track, wheel and bearings inspections that help prevent accidents. This has positioned us well in the rail industry. With this program, we intend to go further when it comes to safe rail operations."

The program, estimated to cost C$10 million (US$9.4 million), will include the acquisition/installation of:

• Thirty new Wayside Equipment System units that detect hot bearings, hot wheels and dragging equipment;


• A new track geometry test car to monitor the position, curvature and alignment of track;


• An optical track inspection system that uses imaging to identify defects;


• More than 30 new brittle bar detectors that identify and flag derailed equipment to train crews, and


• Controlled signaling on certain key rail sidings in our most heavily used corridors to alert crews and dispatchers to broken rail incidents.

CN says it has more wayside detection technology than any other railway in North America and has increased that capability by 30% during the past five years. CN has also increased the frequency of its ultrasonic rail flaw inspection by 70%.

Said Vena, "The application of new detection equipment and modern safety technologies will improve the coverage of our network. The technology we're deploying will keep us ahead of the industry in this field and strengthen our solid safety performance even further. Advanced technology, rigorous safety process and the continued strengthening of our safety culture are the key foundations of our unwavering commitment to safety.

"Our safety focus is producing solid results," Vena continued. "CN's main-track accidents declined by more than 50 per cent between 2002 and 2012, a year in which CN recorded the fewest such accidents in its history. That's a good performance but we know we can, and have to do better still."
