The Rails Shrink the Land

~1830 CE

History · Contemporary · Holocene · Meghalayan

From about 1830, steam took to rails, and distance grew cheap. The effects have been computed: in the United States, the rail network's growth from 1870 to 1890 raised farmland values wherever it improved a county's access to markets, and deleting the 1890 network in a model wipes out around 60 percent of agricultural land value. In Britain, the time that trains saved travellers came to be worth more than a tenth of national income, once railways had turned travel into something the masses did.

Why it matters

Railways made geography negotiable: where the line went, farms, towns and prices reorganised around it, and where it did not, places quietly lost the century. They created mass travel, national markets and standard time. And they remain a favourite demonstration in economics that infrastructure is not a background expense but a source of growth, whose gains are largest precisely where the economy works least well.

Dating & uncertainty

The date here marks the dawn of inter-city steam railways around 1830; the measurements span the decades after. In Britain, the time trains saved travellers passed a tenth of national income by 1912; for the United States, removing the 1890 rail network in a model erases some 60 percent of agricultural land value, and newer work argues the aggregate productivity gains were larger still.
