Whislt one train op isnt great, I think on Saturday they opened up Colossus, Nemesis, Saw and Rush all till 6:30 to try compensate for it. Dont like that fastrack is sold for it whilst on one train though.
Id like to see the effects back up soon, but id guess that some of the engineers working on it to try get it back up to 2 trains will be the ones who eventually look at the effects.
