“As for maglevs: they are a cute boondoggle, but not worth the expense. China isn't building them anymore because the cost isn't worth it. ” I mentioned that they are building them and provided a link. They are focusing on the cheaper low-medium speed maglevs. You don’t need 150 mph trains to travel within a city, or metropolitan area. 120 mph is sufficiently fast. Newark airport to JFK, for example, is only about 35 miles. Park at Newark and fly out of JFK. Manhattan is 20 miles long. How about an express, with a few stops, that covers it in 20 minutes?
