At any rate, the US has a dramatic problem with lack of Rail infrastructure, not to mention light rail and tram services. (how do I know?

Short distance flights are, with the state of fossil fuels and climate change, pretty stupid in every sense. As for profitability of rail services, apart from the fact that I consider public transport to be a PUBLIC SERVICE for which we pay taxes, not a for-profit business endeavor, profits are easily calculable with increased use at every inevitable rise in petrol costs, until driving becomes undoable altogether. Investment at this point is essential.
