Add some variety to your train set with the BRIO Short Curved Tracks set. These four solid wooden pieces are 3.5 inches long and easily snap together or to other BRIO track pieces. All four together form a U-turn, though they can of course be used separately. Unlike other BRIO tracks, the curved pieces have runners on either side, so you can make your trains turn right or left without buying another set of tracks. --Rob Lightner4 pieces3.5 inches eachworks with any BRIO track3+
