Good question.
We always assess the situation in terms of passenger safety. For example, disembarking from a train stopped on a track is complicated and difficult. We need to think about seniors and people with reduced mobility, for whom it isn't always easy to walk on the rocks along the track. Sometimes, the track is surrounded by forest. We assess all this in real time. Obviously, the easiest situation would involve a platform, a level crossing or something of that nature.
I'll let Ms. Toporowski finish answering the question.
