Thank you, Mr. Soroka.
Basically, what Kyle was saying is that we are investing the majority of our money in technology. Some of the technologies we have are mature technologies. They're ones that you may not know are out there, but they're wayside inspection systems that have been around for a long time. They measure wheel heat to prevent any derailed cars.
We have slide detectors, for example, most common in the mountain territories, that will notify a crew if we have an avalanche of snow or if stone is starting to slide down a cliff. We have what's known as a dragging equipment detector. This tells you if there's something dragging from the undercarriage.
Where we're moving further in technology though is at CN we have built an autonomous track inspection program. You'll see them on trains. They're a small boxcar on the back of a train that highlights safety on them. What's in them is computer equipment that takes multiple measurements of the rail and uses a lot of track geometry and algorithms and feeds back a report directly to our wayside personnel.
The benefit of this is we can develop algorithms that can use predictive analytics when we're trying to schedule our maintenance. If you have these railcars moving across our system 24-7, 365 days a year, just think of the increased frequency of track inspections.
The second one which we're dealing with right now and have invested in is automated inspection portals. There are actually seven at CN, five within Canada—four right here where I am in Winnipeg. These are ultra-high definition panoramic cameras with high-density LED lights that capture a full 360° view of a train as it's going through the portal at track speed, regardless of weather. Even in the blizzard conditions we've been dealing with in the last couple of days in Winnipeg, they provide crystal-clear images. It checks the entire train, including the undercarriage.
Based on a set of algorithms that we have designed, it communicates to our mechanical team if there's an issue with any of our railcars. We'll be using this technology to reduce the likelihood of a railcar derailment.
Think about where we strategically place these types of portals. We have trains arriving that are coming up from the U.S. out of North Dakota or Minnesota and trains that are passing from coast to coast across Canada, moving up towards Toronto and the Atlantic provinces via our northern Ontario district. They're all checked. Every single railcar that moves through here is verified.
