you do realize that across the US there is nearly a hundred billion dollars of deferred maintenance to light rail lines used in most cities? Look at all the maintenance issues just with NYC subway system which is considered the best in the US. Plus they have the ability to provide rides for less than cost and recoup it by other means, taxes on unrelated activities.

I find this idea really odd that a private company is going to cut corners. The fact is it has been the public projects that have cut corners. A private company always has the incentive to stay profitable and cutting corners is not how you play the long term game. Unlike the public held transport agencies they cannot just ask for a bailout or tax increase
