The Working Wooden Locomotive Building Set

This is the wooden locomotive kit that enables an amateur engineer to build a working model without the use of glue. The kit contains 405 components including laser-cut wood gears and metal hardware that fit together like a puzzle. The plywood pieces form a locomotive and passenger car that chug along the included track while providing an intriguing visual display. A key-wound spring powers the locomotive. Ages 14 and up. 5" H x 7" W x 34 1/4" L
