Thank you.
Just before we go on to our last few questions, Mr. Beatty, in your opening remarks, you talked about conductors or engineers on the train and about 60 demerit points, but you didn't go into any detail.
When you're talking about demerit points for driving a car or whatever, you get two if you're driving 10 kilometres per hour over; three if you're 15 kilometres per hour over; three for not wearing a seat belt, and so on. You have a total of 15, and well before that, you actually have to go in and write your licence. So 60 seems like a lot, but I don't know how the system works, and I was wondering if you could explain a little more about how that works.
