Yes, the issue is the chasses. Removing the containers from the port frees up the chasses that are currently holding them. And why are you taking all the containers to Dallas? They aren't bound for Dallas, they're all going to different places, which is why you need a fleet of trucks to get them to their various destinations. The trains are just to get them to the new pickup point. It's a temporary measure to free up chasses until the logjam at the port works its way free. He only mentioned Dallas as a way to say "The trains aren't running their full usual cross-country route [i.e., all the way to Dallas]. They're just running the 1st leg back and forth over and over again so that the containers can be moved as quickly as possible." The goal was never to get the containers to Dallas.
