transantiago: before and after

hello people! today i'm going to talk about the transantiago system of public transport in santiago. personally I'think that transantiago is better than the previus system. but when transantiago started was the worse system. transantiago needs a lot of planification and money. when it started none of this requeriments existed. everyone knowed that transantiago would be regular in the beginings but nobody knows that would be a really disaster.
