Both border agencies have deemed our train relatively low risk, given our guests are of the age that they are, 65-plus world travellers. All have come into the country with passports, so they're relatively low risk.
With pre-clearance our operation wouldn't change a lot today as far as the actual train operation, but it would become more consistent. We lock it up once the guests get on. We don't unlock it except for emergencies, and we stay locked up all the way to Seattle.
