As you push this train down the track, the cogs on its wagon happily spin around for a truly dynamic play experience! They can also be removed for play involving loading and unloading. Magnets link together the engine and wagon. Get longer trains on to the railway tracks. On each of the cog sets is a metal pin that allows it to be picked up by Hape’s magnetic cranes. Suitable for independent play or compatible with Hape and other leading wooden railway brands.
