It's not inconceivable. It's certainly not their core business.
I think both companies would say that their core business is freight in a continental context, and that is where they're focusing now, but they're in business to do business, and if someone were to come along and say, “Here's a business proposition; it may leverage your assets, and it may make sense from a business perspective”, I would be surprised if they didn't look at it seriously. However, I would say that it would be an unusual situation. I certainly would not see those companies shifting their basic corporate strategies.
