It's interesting. I've spent some time in Japan, and of course the Tokyo station handles 850,000 people a day, and yet Narita, which is their international airport, is actually a ways away. So it isn't necessary that the hub has to be where the airport is, as long as that feeder line is there. I think it's important that is planned.
I'd like to direct a question to Mr. Fitzgerald before we finish up here. I live on the west side of the Rockies, and we don't get winter on that side and you do on the east side of the Rockies. I've found that out since I've been an MP here. The controls that you install for the ETCS systems, have you put those in place in Russia, for instance, or places where there are colder climates? And does that affect the reliability of those systems?
