Water supply shaped American and British steam railways

Railways followed rivers partly because early locomotives consumed large amounts of usable water, while Britain's denser supply network permitted different engine choices.

Notes

The geography of early railways was tied to the water demands of steam locomotives. American lines often followed rivers because those corridors were easy to survey and offered regular access to boiler water. Those conditions may have helped produce different American and British locomotive forms, since Britain's smaller area could support a much denser network of water supplies. The comparison turns a paddle-steamer discussion into a broader lesson about how infrastructure and geography shape machinery.
