rail map

This thread is made for four Qbam maps. A Rivers and basins map, a Roads map, a Railroads map and a height map. I am too lazy to complete any of the above by myself so I made this thread so that the internet can complete these for me.

Since no such thread has appeared in the Alternate History Maps and Graphics subforum, was wondering whether anyone has tried their hand at making Railway maps? Particularly those derived from projects that did not go anywhere in OTL or were repurposed in later schemes.
