This reminds me of when I went to Wicker Man’s opening weekend back in 2018. As a moment of reassurance; if I had a pound for every time that coaster broke down on 24th & 25th March 2018, and in 2018 in general as it had a pretty rocky first season, I’d be a rich, rich man!
When I queued for the coaster on the Sunday morning, it opened over 2 hours late due to its issues, it broke down constantly (I heard the phrase “the Wicker Man is currently experiencing a delay and we have ceased our ritual” an awful lot that weekend…), and when I finally got on it after over 4 hours of waiting overall, it broke down in the tunnel at the end and I got evacuated, with the queue also being evacuated and the ride being shut for a good bit of time.
My point here is; new rides having problems, even those requiring multi-hour closures and queue evacuations, is not at all unheard of. I’m quite hopeful that this isn’t a major issue in the slightest and is just run of the mill teething problems that any new ride will have.
Personally, I’m reassured by the fact that they were supposedly able to send empty trains at all; if it had been something that had broken, then there’s no way they’d have sent trains around, surely?
