HELP!!!!!!!!!! I am stuck in the train I play 10 minutes and the train..

Well it doesn't depend on time when the trains stops. you have to battle the man bloccking the door to the next car and win then go into the next car and battle the guy who comes over to you. When you beat him the train stops. but this is only if this is the first time you have been on the train.

Well it does not depend on the time you spend on the train, it depends on when you defeat the people on it.
When you are in the first cart there will be 4 people in it, 2 train announcers and 2 duelists, To carry on to the next train cart you must defeat the train announcer on the left (beware at this level his cards have a considerable defense) the other people there are duelable but are not required. In the next cart you will meet Panik, after some exchanging of dialog the train will go into a tunnel making the room dark (the darkness gives dark, fiend and dream type cards strength,coincidentally his deck is based on fiend and dark monsters -_-).
When you defeat him the train will stop, however there is another cart with a rich family who can all duel, they can give some rare cards if you ante up.
They will not be there later on in the game.

Tip: to get Meteor B.dragon (Atk:3500 Def:2000
8 stars) constantly ante up against the 2 duelists in train cart 1, these will not be here later on in the game. (make sure you don't choose a low level monster as an ante or you will have a greatly decreased chance of getting Meteor B.Dragon.)

Push the 'R' trigger on the GBA or emulator and the guard on the left will battle you, the 'A' button doesn't make him battle you like it does with other people which was wierd.

Walk up to the man blockin the door. Regardless of what he sais,you
must challenge him to a duel(the man on the left hand side) press right to challenge
