Spirit Tracks train is upgradeable
Game set a century after Hourglass.
The Legend of Zelda: Spirit Tracks is set "about a century" after Phantom Hourglass and the train you ride around on is upgradeable.
That's all according to Nintendo of America's Kit Ellis, who spoke to G4 (thanks vg247) about the game's setting and new features.
"Spirit Tracks takes place about a century after the events of Phantom Hourglass, so it's a different Link but sort of in the same world, so you can actually see some sort of homages to the previous game throughout the story," Ellis said.
"As with any Zelda game, exploration is a big part of it, and you're not just going from A to B in the train, you're uncovering secrets and driving to new places, and the train you can actually upgrade as you go along. Eventually you'll even be able to lay your own track and do a bit of exploration that way as well."
The Legend of Zelda: Spirit Tracks is due out for Nintendo DS on 11th December in Europe, and you can read more about it in our recent Spirit Tracks hands-on preview.
