I want to start by saying that, really, this is an isolated incident, because we have 20,000 train starts every year. The majority of those are to the satisfaction of the clients who travel by train, and those customers keep coming back on our trains. I wouldn't say that the confidence of the travelling public is not there.
Of course, this event is unacceptable. Although isolated, it's something that we are addressing very seriously, and we want to make sure it does not happen again.
We're taking measures. We talked about supplies of food and supplies of water, but if the measures we've taken now to make sure this does not happen mean that it doesn't happen, then the supplies of additional food and so on become moot at that point.
