Just to be clear, in this case, the hours of service that we're talking about were those of the Via crews that were brought in to relieve train 55. Martin can comment on this, probably way better than I can, but there is coordination and planning. Technically, schedules are planned in such a way that you don't run out of hours. There's a transition that's affected, but in extraordinary circumstances like this one, it could play out a little bit differently.
Maybe my colleague Mr. Tran could respond to that question.
