Phantom Train, or GhostTrain, is a boss in Final Fantasy VI. It is battled at the front of the Phantom Train, and is the main engine of the train, an undead and sentient entity rather than just a machine.
Its attacks include the dangerous Diabolic Whistle, which inflicts a random status ailment on each party member, Acid Rain, and Saintly Beam, both of which do mediocre magic damage to the entire party. It will only use Diabolic Whistle regularly if only two party members are alive, so if the player was able to board the train with Shadow and keep all the party members healthy they can avoid the risk. As an undead enemy, the Phantom Train can be killed instantly by using a Phoenix Down.
The Phantom Train is vulnerable to Sabin's Meteor Strike, which is an oddity as most large enemies and bosses are immune to the attack. Sabin's ability to do this has become an inside joke among fans of the game due to Meteor Strike's original SNES translation as "Suplex".
