It's not a new technology but has been around since the late nineties, early 2000s. It was initially brought in to use in yards in building up trains and in switching yards for what used to be hump operations. It's now flat switching. That's since expanded to outside of yards and to other yards for switching industries around yards, for which it was never designed. It was originally designed for flat switching in yards that build big freight trains. That's since expanded, and now it's expanding again. CP has announced that they're going to move it out to do all the road switchers and main line operations with it. That has a significant impact that we think is negative.
