Build a tunnel. Build a station. Build a multi-level masterpiece! The Block Platform cleverly combines wooden train tracks with classic building blocks/bricks like LEGO DUPLO to facilitate open-ended creative play. Use it flat on the building surface, or snap bricks underneath to support the tracks while you build upwards. It's easy! Compatible with all major brands. Large LEGO DUPLO bricks or small LEGO bricks can snap onto the top of this platform. Only large LEGO DUPLO bricks snap to the underside of this product, small LEGO bricks do not snap to the underside. Please note: the Wooden Railway Block Platform does NOT utilize "tabs" to support the track, but rather it positions snapped-in bricks underneath to cleverly and easily create a support surface to elevate wooden tracks.
