I'm afraid to build railroads. Is it worth connecting cities by railroad? Is there any benefit to putting a railroad on a mine or lumbermill or any other tile? I used to put a railroad on every tile in my territory ... starting with the mines, then lumbermills, then connectivity, then everywhere. In CIV V they obviously wanted to stop people from that sort of behavior. Now I'm not sure I want to build a railroad at all. Does anyone have a specific strategy for railroads?
