One of the real keys—I didn't get a lot of time to talk about it—is the Internet of things technology, the industrial Internet of things.
I'll give you a quick example. I did an investigation a couple of years ago. A runaway crude oil car collided with a standing train and derailed a bunch of cars. We went to look at the car. There was this device on top of one of the tank cars. I thought to myself, “I wonder what that is.” Somebody used to call me “Inspector Clouseau” and I'd say, “I'm not Clouseau, I'm Columbo: I have one more question.” I went to the source and found out what the tool did. I found out that it took GPS. It took G-forces in three dimensions. It gave the peak impact duration as well, and the time. We got data that we couldn't have gotten otherwise.
When we put that data into the system, what we found out was that the tank car had experienced a force four times the design capacity of the car. Then the obvious question becomes, how come this thing didn't make the six o'clock news? Well, again, because we got this data, we found the telemetry data: the impact duration was only five one-hundredths of a second. You had this massive impact on the car, and then it released before it had fully crumpled. It had actually buckled. There was a small buckle in the car, because essentially the train had hit with a crumple zone and the forces were transmitted through once they got the locomotives moving.
The point is, why aren't we accessing that data? Ask yourselves. Do we say that obviously this is way too expensive to get? These sensors on a car cost $150 a year. It's chicken feed. Why that's not a requirement on every tank car, I don't know. On the comparison between pipeline and rail, for instance, I don't think there's anything inherently that says—I investigate both—one is safer than the other, except that the pipeline has sensors in every foot of it and is being constantly monitored. But for that tanker train, it leaves the station and gets to the other end, and there are few steps along the way where they have a look at it. The reality is that you could be watching it in the same way, and one tank car derailing is a lot different from having 30, 40, or 50 derail.
