On: Air travel’s sudden collapse will reshape a trillion-dollar industry

What does "15m/mile" mean?

I suspect that means 15 million dollars per mile of rail. It should depend on where the rail is being installed though, because for paved asphalt roads, the price per mile can vary from 500k per mile per lane in a rural area, to north of 10m per mile per lane if you’re in a densely populated urban area
