When we want to visit other cities, it will make us spend so much money, especially for fuel. Not just that, when we want to go to somewhere which is far from us, it will take so much time. In order to minimize that kind of problems, people think that the government should have spent large amount of money in order to construct new railway lines for very fast trains between cities. The other public opinion also believes that the money should be spent on improving existing public transport, like buses, existing trains, taxi, and many others.
