Area per kilometer of railroad in Europe by region 1913
In 1913, Western Europe had one kilometer of railway line for every 10 square kilometers of land, which was more than double the rate of Central and Eastern Europe, and roughly 2.5 times the rate of Mediterranean Europe. Due to its vast size and sparse population distribution, Russia had the smallest railway network in proportion to its size, with one kilometer of rail for every 324 square kilometers of land.
