"Predicting rail costs not a simple task"  OK, that's true.  But here's the thing....we're not talking about nickels and dimes.  We're talking BILLIONS of dollars!  If we're building a new building and the cost overrun is a half million dollars, I don't think we would even blink an eye.  But a project that was estimated at 3.2 billion is now projected to cost OVER 10 BILLION?  I would say that's some pretty poor predicting!  The other issue is that back when the idea was put out to vote, it was with the idea that it was going to cost 3.2 billion.  Those who voted YES all believed that.  How would it have turned out if it was stated that the cost would be over 10 billion?  Would we still have voted YES?  Or, was it a strategy (by PRP?) to UNDER estimate it just to get us to vote YES?  Hmmmmm!  The average voter is not a construction expert, so whatever they estimated we believed.  I am positive those in the industry knew it would cost a lot more than 3.2 billion!
