Ah, that stinks.
I think a better worn look would be to create a partial overlay (use the mask tool to select where you want the tracks, and then copy and paste the wood planks layer, and apply a slight desaturation w/ brightness & a decontrast), so that you wood all stays the same color and such, but where the wagons have run over, it looks worn, rubbed away/frayed/splintered/whatever.
Now I really want to try doing that, but I don't have time before school starts
Perhaps later...
