I can understand fixed sites for natural resources. The coal mine is where the coal is. But historically, the sites chosen for manufacturing industry are determined by what is logistically feasible. The factory goes where the railroad is, not the other way around (most of the time).

I don't know if OpenTTD allows it but in the original TTD it was possible to plop down factories at will (but not mines, farms or oil wells).
