Generally speaking, decisions are made on the basis of a business case that justifies the investment. In our sector, investment in rail infrastructure is very costly. I mentioned investments of $4.5 billion just for maintenance, in addition to targeted investments at a few locations last year alone. So we're talking about $4.5 billion in a single year.
I would simply say that, before investing, railway companies make sure that the investment will be profitable. That's a given.
