This is most likely more political "hot air" of which there is plenty here in South Florida. I don't they are even close to having the money to do anything here and believe me it will take a huge amount of money to do any commuter rail on the FEC right of way.
I am not saying that it won't happen someday and heavens knows we surely need more and better public transportation here but I don't think it will happen anytime soon and probably not for many years. The politicians here are always having forums and meetings about public transportation but so far in the 13 plus years that I have been here, nothing has gone beyond the talk stage except when they put down the second track on the existing Tri-Rail line a few years ago.
The highway lobby is much too strong to allow very much to go into commuter rail or any other rail here in Florida for that matter and I think that will be the "rub" here too.
