With BRIO cargo harbor set you can sail the container ship across the water and arrive in the harbor with cargo. The battery operated train is waiting on the BRIO train track to get loaded with help from the multi-function crane. Slide open the boxcar doors and hide the cargo inside for safe delivery. As the ship leaves the harbor, do not forget to open up the bridge to allow it to pass by the tracks. Compatible with most other wooden railway sets. Ages 4+
