You know that sounds like a job for some simulation software, especially if you could model things like adding intermodal terminals and adding links to the network constrained by the cost of right of way. Even better if you could figure out how to model the politics and market forces, if you could come up with something that helped railway executives make better decisions about the environment they operate in (apparently they lease rights of way back and forth, and the company running the train is not necessarily the one that owns a given stretch of track), you would have a saleable product.
