The Legend of Zelda Spirit Tracks
The next handheld Legend of Zelda game, The Legend of Zelda Spirit Tracks is a sequel to Phantom Hourglass that adds new game mechanics to the popular series, including the introduction of train travel, and a Darknut/Phantom ally to help Link. Controls are apparently like Phantom Hourglass, although that hasn't really been tested.
