Isn't this statement kinda backwards though? Surely the big cities developed along that line due to the natural geography (flat land, near bodies of water and with protection from the mountains) and then once trains first came along, it made sense to connect those cities. It's not that people happen to live within 5km of the trainline, but that the trainline was built there because that's where people lived.
I see where you come from, but I guess it's still uncommon to have a third of a country living on a line
Also, the data looks quite good, which is the main objective of this community
I bet US can get something similar for NE corridor
Switzerland is about as big as Vermont and New Hampshire.
NE corridor is 100m people
for real, more people live in new york alone than do in finland
