Use the launch coaster sprint 500 and make track go where u want and make sure it goes up a big enough hill to gain enough momentum to go back in to the station, then on the end of the station build a straight single straight piece then the game will alow the train back into the station instead of launching back down the track , found this out by someone's super man blueprint I can't remember the guys name but it's Hollywood something sorry I downloaded it just to see if it worked and I found out the secret lol
