We always look at ways to protect safety, but also to manage costs. We would always look at that. Right now, we don't have a one-person crew operation. We are three, except on one quarter, where we're two, where we inherited the collective agreement or the parameters within that collective agreement. So there, it's a two-person crew.
We're always looking at those capabilities, and if there's an equivalent level of safety that technology can provide, for example, true enhanced train control, we would look at that to see if it would work for us.
Right now there are seven rail corridors, six of which have a three-person operating crew, and the seventh a two-person operating crew, but we're always looking at technology alternatives to enhance safety.
