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 Straights & Curves Track Pack also includes two track adaptors, so it’s compatible with other wood track systems, including classic Thomas & Friends(tm) Wooden Railway (sold separately and subject to availability). For even more fun ways to play, this pack includes a poseable plastic cow figure and one track piece with adorable little hoofprints. Kids can connect these track pieces to other Thomas & Friends(tm) Wood train sets and destinations (sold separately and subject to availability) to expand their layouts… and their creativity.
