Why not this...
Download the freeware ScaleRail, ScaleRoads, Rural Landscapes, and RCAP v1 (not sure when v2 will be ready), and what is available from The Golden Age of Railroading. This will give you an idea of what is attainable using some pretty nice stuff and only having 3DTrains, RCAP, and GreatNortherner checked off in the object browser. When RCAP v2 is released it will include a ton of new models, including signals, grade crossings, and water lofts and decals.
For your first route don't pick a real place. Just imaging one based off what you have seen on Google Earth (or maps, or books). Lay some tracks, lay 5 in paralelle, make a yard ladder, learn to weld track, and use easements. Placing models down is simple, so after the track I would recommend placing trees and pants which is much harder than you can image.
There are some freeware locomotives available: GP15-1. F40PH, SD7/9, and some of the Britkits offerings. The Golden Age of Railroading has some freeware rolling stock. Learn to make a few simple scenarios.
Then give it to the public (and run like hell as the rivets fly!) and gather some feedback.
Some of the best routes which have stood the test of time (ie they were built in RailSimulator) are fictitious... and small. I recommend following this learn path before taking on something prototyped off a present day or history line (which then demands a higher level of attention to detail).
