Units moving along a Railroad expend zero movement points. Railroads also increase the output of Irrigation or Mines, by 1 food or 1 production respectively.
Workers can build railroads after the discovery of Steam Power, but only if your civilization has access to the Strategic Resources Iron and Coal.
Workers are ordered to build railroads by pressing [Shift-R] or the "Build Railroad" button.
