I believe it comes with the two extra straight rails because if you don't use them for the upper rail at the ends, before the slope, there will be no room for the under rail to get out from under.. With the 2 extras extending the upper rails you can then use curved rails for the lower to get out from under. Its generous of them to include them in the set after all, who could"t use a couple extra straight rails? Nice box and deal T-Real.
Hmmm!...off the top of my head...is this set not the longest item made in the Plarail trains line?
