We haven't changed the speed that we operate at as a maximum speed. We operate our freight trains at a maximum speed of 60 miles an hour, as long as the configuration of the track is such that it can handle it. We have never changed that. It's limited by curvature, the type of track, the area, visibility. We take in a lot of factors when we look at it, so there's no change there.
The trains we've been operating are the normal crude trains, the 100 cars. If it's a unit train, it's somewhere in the 90 to 100 range. We operate trains that are 150 cars. We run grain trains to the west coast from Alberta, Saskatchewan, and Manitoba that are about 150 to 175 cars. The technology has changed. The airbrake system has changed. When I was hired on the railroad, if you tried to handle a train over 100 cars with the airbrake system that was in place there, you just would not be able to release the brakes, you would not be able to handle it that way. It wasn't the issue.
We also have DP locomotives that we can put on the train in two or three locations, front and back, operated by one person in the front. The technology has come to the point that we operate our intermodal trains most days at 8,000 to 10,000 feet—I apologize, we're still using miles and feet. But we operate them every day at that length. We run coal trains going to Prince Rupert as big as 220 cars. It's a safe way to do it. We've been doing it for a number of years. They're heavy cars, but that's what the infrastructure is built for. It makes us efficient.
