Effective mass transit helps to decrease pollution and conserve energy. However, in order to work, the transit lines have to "go somewhere". At some point, the revenues the systems generate have to cover a significant part of the operating costs. I do not support ideas like the high speed train between Madison and Milwaukee because of the large subsidy that would have been required to operate it. The fact is that for most people, traveling between the two cities their automobiles would have been faster and less expensive.
