Add some space for your trains to use with the BRIO Medium Straight Track set. You get four durable wooden snap-together pieces, each about 5.5 inches long with runners for wheels. The tracks fit together nicely, and BRIO trains run smoothly even across joints. Of course, you"ll need some curves--or a complete set--to keep your trains from derailing at the end of the straightaway, but these are great for lengthening preexisting tracks. Like all BRIO products, they"re guaranteed against manufacturing defects for life. --Rob LightnerIncludes 4 pieces of a trackEach measures 5.5"Works with any BRIO trackFor ages 3 and above3+
