UNIQUE 3-WAY TRANSFER TRACK – This wooden train track set splits a single line into three side-by-side wooden train tracks, then merges back into one, giving toy trains room to pass, swap cargo, or pull aside for an oncoming train. SMOOTH CROSSOVER GROOVES – Carved lateral grooves let train cars and engines glide between all three lanes, so wooden trains can switch tracks mid-route for endless imaginative, dynamic play. UNIVERSAL FIT FOR EVERY MAJOR WOODEN RAILWAY BRAND – Built as a compatible wooden train track accessory that connects with Thomas wooden railway, Brio track, Melissa and Doug wooden train track, Hape train track, KidKraft, and most other standard wooden tracks. SOLID WOOD CONSTRUCTION, BUILT TO LAST – Made from sanded, kid-safe solid wood (not flimsy plastic), this wooden train track piece is sturdy enough for years of play on any wooden train table or wooden railway set. EASY WOODEN TRAIN TRACK EXPANSION – A perfect extra train track piece for any wooden train set; add it to your existing wooden train tracks for toddlers 2-4 and older kids to build bigger, more creative switch-track layouts.
