The wooden Sand Tower includes straight and curved track on the base to increase placement options within a track layout. Your little one can roll the carriage in line with the tower, lift the barrel and watch in delight as the sand load slides into the awaiting carriage ready to be transported. Develops dexterity, imagination and an understanding of cause and effect. Most other major wooden railway brands are compatible with Bigjigs Rail. Made from high quality, responsibly sourced materials. Conforms to current European safety standards.
