I really can't speak too much for the U.S. railroads. I know there's a lot of push for electrification on passenger lines. The northeast corridor is a good example, with Amtrak. I'm not aware of a lot of major freight traffic or freight roads or rights-of-way that are being electrified in the U.S. They face the same hurdles we would face in terms of the infrastructure investment costs to make it happen.
But to Michael's point, I think that on the commuter side, if you have a dedicated right-of-way, which seems to be more and more what's happening, the opportunity to electrify does make some good sense.
