westtexas, I agree with you. The other factor is the cost to the build the infrastructure in the first place. Which is the problem Charlotte is facing right now. They want to build the 2nd line, but they don't have the money for it and they the state won't allow them to raise the money for it. So in some situations it's also not just an issue of the city wanting it or not, but in this case the state preventing the city from building it. That line would be great as it will go from downtown Charlotte to the major university (UNC Charlotte) on the east side of town.

As for oil it's self, I wish we could pull it off the futures/commodities market as the speculators, IMO, are the biggest issue.
