That’s still not cheap by any means.Doesn't this include the trains and the stations in the 1.6 billion. 378 cars and 17 stations would be a significant part of the cost. 2 million a car is 756 million and stations is anyone's guess, say 5 million each, so total for cars and stations is about half the cost of the extension. So that leaves 15 miles at 800 million or about 53 million a mile.
