The revamped track connectors fit together easily, allowing children to build their own layouts – and their own stories – by themselves. With this unique connector design, there's no wrong way to build! This Expansion Track Pack also comes with two track adaptors, so it's compatible with other wood track systems, including classic Thomas & Friends™ Wooden Railway (sold separately and subject to availability). Kids can expand their railway layouts and their creativity by connecting this collection of curved, straight and turnout track pieces to Thomas & Friends™ Wood destinations and train sets (sets and destinations sold separately). The handy turnouts let children build in two different directions, and easy-to-use knobs allow them to choose which track their toy trains take. With six straight track pieces, six curved track pieces, four turnouts, two ramps and two adaptors, the possibilities are as limitless as a child's imagination.
