Obviously, if we have to cancel, the sooner we can inform the passengers, the better. We had to exercise that through the derailment portion of time, when we were making sure we could advise passengers the day before if we had to cancel their trains. That was to avoid their having to potentially come to the stations, and so that they could evaluate alternative scenarios for their travel needs.
That was one of the key learnings, and it's one that we'll apply more diligently in the future.
