Exactly. Even the track technologies and the signal systems have evolved significantly, and they are continuing to evolve. In fact, the previous U.S. government made a decision to require positive train control on the current freight systems that are also accommodating passenger systems. This is going to be quite revolutionary. We don't have those in North America right now. They're used in Europe. Doing this will allow for optimization of the shared infrastructure and elimination of many safety concerns. If you go ahead with this, you want to make sure you're getting the best technology, whether it's track, car, or locomotive.
