Anyone played Railroad Tycoon?
Check out my post on road & rail in the Civ3 Essential ideas forum...
Basically, you build a station/port/send a ship to a resource and then ship/rail the resource to a city or another resource producer.. For example, you build an oil refinery, so you send a ship to an off-shore oil rig, bring it to a port, which sends the oil by train to the oil refinery which produces petrol which is sent to cities or for export..
Of course, it would be too complex to have to control the trains yourself.. It could be automated.. All you have to do is make sure the destination & source are connected by rail, and that they both lie in the catchment area of some station...
