Using this track set is easy. First, set up the track and place Kana on it. Connect the battery to make Kana move. Flip the switch, and watch as Kana starts her journey to the cargo dock. The cargo dropper will load the cargo into Kana's car automatically. You can collect and connect this track set to other non - wood Thomas & Friends track sets to create a larger railway. Remember, additional track sets are sold separately. For kids aged 3 and up, adult supervision is recommended during play. To maintain the set, keep it clean and dry. Avoid exposing it to water or rough handling. If the battery runs out, replace it with the appropriate type to keep the fun going.
