Yes, I will.
There's an overreliance in the industry on technology and the technology, I've often said, is not proven. An example of that would be in the coal train system that's running from Sparwood in British Columbia out to the coast and back.
We used to perform a safety maintenance inspection on that train at a number of locations. CP was able to convince Transport Canada for an exemption on a number of safety and maintenance inspection rules and the no. 1 air brake test rule because they said we have this technology. They ran a six-month test and the technology proved to be 83% effective. With eyes and boots on the ground, we're 100% effective. The exemption said it will ensure railway safety and it's in the public interest.
It went from arguably 100% effectiveness with our rail mechanics doing the safety inspection maintenance to 83%. This has now been in place for about 18 months and the evidence is showing that it's declined. It's gone from 83% down to almost touching the 60% effectiveness. But our mechanics are still going out.
Also, the overreliance on WILDs, hot box detectors, and cold wheel detectors, those are tools that would assist our mechanics, not replace the mechanics.
CN has wayside detectors about every 12 to 15 miles. CP has them between 15 and 20, and say they're the greatest thing in the world. We still have bearing failures, cracked wheel failures, dragging equipment failures, and all of those would be captured at a safety inspection location. But most of them, for the most part, have been eliminated. That's why we're saying we should have a safety maintenance inspection at least every 1,600 kilometres, so we know that those cars are travelling from one distance to another in a manner that's safe.
In terms of the technology, there's an overreliance and my fear is that there is going to be more and more reliance. The railways are saying that they're not going to fix cars that they don't own. They're in the business of moving cars, not in the business of fixing them, and that's the mentality that drives this technology.
