Just wondering if anyone else has noticed that railroads on irrigated plains, grasslands, and floodplains squares will give you an extra food (at least under democracy havent tested other government types)? This isn't in the civilopedia or the manual that i could see but perhaps its in the readme. Another odd thing about railroads is if you have a mined grasslands with shield and then put a railroad on it you get three shields but a railroad on a forest leaves you still producing 2 shields :crazyeyes . Basically this tells me i should have a railroad on every square (except forest). The odd thing is that Sid changed railroads function in Civ 2 so people wouldn't have boring railroad dominated maps which i thought was great but now we are back to boring railroad dominated maps.
