Someone posted how to make it do this a while ago. If you go to manual dispatch mode, and open the restraints right after you dispatch the train, then they won't close and it'll go round the track like that.
I know how to do that, just hit F9 and enter one after the other and it wil run with the restriants up.
Well acually, make sure your on manual dispatch, then close the restraints, close the gates.
Then hit f9 and right after you hit f9 hit enter and the train will dispatch while the restriants are up. I figured that out a long time ago, its retty funny.
I hope so too, it should be really fun to have the restraints of flying coasters open during the ride. Although I think it depends on whether they know about it or not. If not, they'll probably won't fix it.
