Transantiago: Before and after

Hi all. Today I’m going to tell you about mi experience on the transantiago system, and what I think about it. First, I have to make you know that I’m not from Santiago (I’m from Los Andes), so it’s probably that I had wrong opinions about it.
Comparing both of the public transporting system, I can tell you that they have lots of differences. The system that was before of the actual transantiago system produced lot more pollution, and now it pollutes less (or at least a little bit less). But, it had less people on the buses, and you didn’t have to wait lots of time to take one of them. Now, the system it’s really weird compared with the old one, because now you have to pay with a card called “Bip!”, and not with money, just how it used to be.
I would like to change a lot of things to the public transport system: first, I would make that the coin-pay-way came back, so the people who forgot the bip card use coins instead of the card. Second, I would like that the state controlled the public transport system, so it’s easier to handle all the difficulties of it.
