It would be brilliant and I actually tried to do this very thing a number of years ago. The issue is that the railroads are texture tiles, not objects, so making only a portion of the tile reflective is not an option, (or at least not one that I can sort out). The best I could do was to make the tops of the rails pure white with high contrast, and while this did give a minor improvement when you were within half a mile or so of the rail line it did nothing after that. Keep in mind the tops of the rails are only two pixels wide and such detail is completely lost once you are a few thousand yards away. Because of this even if they could be made reflective that quality would be lost in the distance. The old CFS3 sim engine is a bee-otch to work with and it is actually beyond amazing what the devs and modders have been able to accomplish with it over the years.
