The vanilla tracks are now "iron track type" in Railcraft; however, they can be made of bronze. I suggest removing the bronze to track recipe.

Why? I see no reason to do this. Track should be more accessible, not less.

That is like bronze -> Iron exploit when some other mods allow conversion of large amounts of tracks into iron ingots.

Localization could be better I will admit. Even without the bronze recipe, there is still the Iron, Refined Iron, Invar, and Steel recipes for "Iron" tracks.

As far as I know, its just called "Track" and "Standard Rail", no "Iron" anywhere.
