I cannot give you numbers, but public transport in general is very important. A lot of people are using public transport instead of cars because it's quicker and more reliable, and you're not stuck in a traffic jam. It's much more comfortable. People appreciate being able to work on the trains, for example, and we also have business cars where you can work and use your computer. This is one very important factor.
A second thing is that the population voted to transport freight by train rather than by road, so we are investing into switching freight from roads to trains. Therefore, the government also pays subsidies. This was a decision of the population, because as you know, we have a lot of lorries, and it's not very nice for the people living in the valleys when the lorries are going through Switzerland all day and all night. Therefore, we had a vote that was in favour of transporting freight not by road but by rail. So we're investing money there.
There are different factors: investing money and also investing in infrastructure. If you have to buy new trains and if you have to build new infrastructure, that is also an investment in our economy. On the other hand, we have people's transport that is very quick. We have a system of two trains an hour between the main cities in all of Switzerland. Normally the train leaves on the hour and the half hour, and the train also arrives on the hour and the half hour, so we are always thinking about the whole transportation system. We're not thinking about going from one place to another: we are thinking about transport chains and we are planning in transport chains.
For example, if I want to go from here in Berne to Vals, which is a very nice place in the mountains on the other side of Switzerland, I do not have to look at the timetable because I know that I will have a whole transport chain from Berne to Vals. I will go from Berne to Zurich and then I will have to change. I will have the perfect time to change and then I will go from Zurich to Chur. For the second train, I won't have to wait for a long time in Chur, because in Chur, the next railway company, which is a different one, waits until the train arrives, and then within five minutes its train leaves. I will then arrive in Ilanz. This is the last station. It's a little village in the mountain. In Ilanz, I will take the bus or postal car to Vals.
So I know that when I leave Berne--for example, at half past two--I will have the whole transport chain all the way to Vals. This must not be underestimated because this is valuable. People know they can rely on public transport. They can go to work. Transportation is always punctual. We have a very high punctuality. This also contributes to economic wealth, of course--
