In my opinion focusing on cost versus fares is myopic to the point of insanity. As long as we're laser-focused on the economic viability of rail we'll never see any of the other benefits.
We have a responsibility to future generations to not just keep things the same but to make them better, and I think rail does that. If you look around and you dislike your current mode of living, hate your commute, and want to have access to cities, then guess what rail is a solution for all of that. It takes decades to see any real benefit from it though, which is why nobody ever goes for it.
