They'll still be on one train though, completely negating the great idea by having the rides pretty much stop for 30 minutes so they can get the second train on...
I agree that the time it takes to add second trains can be pretty excessive but unfortunately if all rides are to be open for park opening time then engineers will only have time to check one train and then carry out the second train check once all the other rides have been signed off and the park has opened. This is what I've been told by the park anyway and, to be fair to them, it does make perfect sense. The only way to open coasters on two trains would be to have stagerred openings so that the other smaller rides can be checked later. People on here would complain if they did that too. Thorpe can't win.
Many parks get all of their coasters open on time and at full capacity. It's a theme park, and if a major theme park is not able to do this then they have flaws. My opinion on the matter anyway.
Or... they've not announced it just yet. Nothing unusual about that. The Swarm was announced in the August prior to it opening. There's not some crazy reason linked to budget cuts for everything that you perceive that should be happening that isn't, it's all been painstakingly planned out for months, or years. Wait.So, half the rides are closed, and there has been no marketing for a major new ride set to open next year. Either laziness, bad luck, or budget cuts.
