The handsome Hogwarts Express™ locomotive can be run on its own or coupled with two cars—a coal tender and a passenger carriage. The Hogwarts Express™ tender has an empty coal compartment in which you can store the train's wind-up key or other small objects.  The locomotive is the driving force of the model, with its metal spring engine and gears that transmit power to the moving wheels. The locomotive is wound using a special key (there are winding slots on both the left and right side of the engine), but first be sure to twist the smokestack to the "Stop" position. Once the spring is wound, hold the model while twisting the smokestack to the "Start" position, then release and watch the train pull out in a straight line. Look at those beautiful train engine wheels and coupling rods in action! The model is rated "Advanced" difficulty level with an estimated assembly time of 7 hours. The locomotive can be assembled in about 3 hours, giving you a head start on imaginative play! This DIY wooden model kit consists of 504 parts that are laser pre-cut into wooden boards. To assemble, simply remove the pieces from the boards and snap them together following the detailed, illustrated instructions available in 11 languages. One of the great things about our models is that no glue or special tools are required—everything you need for assembly is included in the box.
