Supertrain looked like it had potential but NBC screwed it up big time. I remember seeing promos with train racing out of the Grand central tunnel all the time and watching Express to Terror then it disappeared. If NBC hadn't rushed it through production and let the writers make decent material it might have lasted longer. I wish someone would bring it back and get it right this time. Retooling a show is usually a death sentence for it. Why did they change things after three episodes? If your gonna spend that kind of money on a show you have better keep at it until it works. NBC put all their effect into getting the effects to look realistic but never tried to fix all scripts before any were filmed. I am guessing most of the screenplays were first or second draft versions.
