The Phantom Train serves as the boss of a rather memorable dungeon in Final Fantasy VI, which involves the party of Cyan, Sabin and (optionally) Shadow trekking through its various carriages, fighting demons and spirits until you reach the main engine. This fight can be fairly challenging (especially if you don't have Shadow in your party, since Phantom Train uses an annoying status-afflicting attack called Evil Toot/Diabolic Whistle if there are only two members in your party)... that is, unless you know a simple trick to defeat this boss in one go.
