The Transantiago system is definitely a theme very commented and criticized between the people of Santiago.
To compare the old with the new transportation we must take into account a few points, one of these is the cost. In this days, if you don´t have an student pass, you have to pay a big ammount of money in compare with the old system, but a good thing in this point is that the way of paying now is a lot easier and requires less time. You have to use a BIP! card charged with money instead of pay to the driver with coins.
Becouse of these the delinquency has decreased, the offenders has no longer money to steal, and also the passengers can travel calmer.
A bad thing is that the cover of the buses is very limited, and most of the time I have to take more than one bus to reach my destination, for example, to get from the university to my house I have to take two buses and the subway, sometimes this take me like one hour and a half.
But I can´t say that my experience is bad, I didn´t use a lot the old transport system, so now I´m very used to the new one.
Have been many campaigns to improve this system, some of theme have worked and some do not. I think that an important thing that we can do is to be tolerant and patient, and complain only when is necessary, the authorities also have to do their part, they have to take into account our needs and make more campaigns to keep improving Transantiago.
