When it comes to freight car safety maintenance, we can look at how it's different. In the airline industry, when an airline mechanic says, “This plane ain't leaving, because the bearings are bad on that nose wheel”, do you want to know what happens? It doesn't leave. And do you know what happens when they say they have to change planes? Everybody says, “All right.” When they say the bearing on the nose wheel is worn out, everybody says, “Okay”. In the rail industry, we could have a front-line supervisor who worked yesterday at a 7-Eleven but is now my supervisor and has powers under the freight car safety act to overturn my decision to say that a freight car is unsafe to move.
When it comes to the maintenance issues, thankfully we haven't seen too much causes of derailments related to maintenance of the locomotives and the freight cars, but I think we'll see more and more of them. The railways are relying so much on technology—on hot wheel detectors, on cold wheel detectors, on pounding or wayside detectors—but I think there is nothing better than a mechanic as opposed to somebody else looking at a freight car.
