American cities are not the only ones building insane rail projects. Melbourne, Australia’s largest city, is currently building a 56-mile (90-kilometer) suburban rail line. Once projected to cost AU$50 billion (about US$32 billion), the projected costs have risen to AU$125 billion (about US$79 billion). Although construction has already begun, the city doesn’t expect to complete all 90 kilometers for 25 years, by which time the costs will probably have risen much higher.
