Question

What year where rail roads inveted?

Answer 1

Steal rails were first used in 1768.

Answer 2

As early as 1550 there were wooden railways with wooden wagons called wagonways. By 1776, iron had replaced the wood in the rails and wheels on the carts. Wagonways evolved into Tramways and spread though out Europe.

Answer 3

Railways were introduced in England in the seventeenth century as a way to reduce friction in moving heavily loaded wheeled vehicles. The first North American "gravity road," as it was called, was erected in 1764 for military purposes at the Niagara portage in Lewiston, New York. The builder was Capt. John Montressor, a British engineer known to students of historical cartography as a mapmaker.
