Why Trains Suck in America

Well I know in Melbourne, Australia our trains are horrible. We have our normal commuter trains called metro which are always late and the line I have to catch, the train comes every 20 min. Compared to Japan when they are 95% on time and come almost every 5 min on every line. And the only real type of express train we have is Vline and compared to other express train it is really bad.
