There should be no population center without a rail center. I don't deny that last-mile would still be on roads, but that's very different from the present state of affairs. My lazy googling suggests that 40% of freight movement is via rail in US. I can't find a full breakout, but the same site goes on to claim rail is only 1.7% of GHG, which means most of the rest is traveling by road, since waterborne freight is generally more efficient than rail.
