    I was told the weight thing and the trim brakes are all to do with if it engages with the 2nd lift hill too fast it can trigger an emergency stop leading to a full ride evacuation

    That is indeed correct. :)

    Basically a proper trim brake would mean it could operate in whatever state. Very surprised there isn't one later in the circuit or it modified slightly to remove such a restriction.

    A proper trim brake needs to know the speed of the train but as the first one is so close to the lift it hasn’t got enough time to calculate the speed.

    Anyone know why 13 has been closed most of today?

    I have no idea if this true. But this is on Twitter today. Best to click the thread to see all the tweets.



    And this was also from yesterday.

    Considering the tyre drive lift hill doesn't have-roll-backs, that's entirely possible, especially if the lift stops and the tyres are wet.

    If there’s truth in this then this isn’t good, but surely there would be a little more media presence?
    Thirteen’s lift hill is drive tyre, not chain. I’m not hugely technical surely there are anti roll back features if the lift hill were to fail?

    Does this mean it will be closed for the rest of the season? I've not see any media coverage on this though.

    I have no idea either, but there must be some form of anti roll back? If this account is true then something has gone wrong.

    Perhaps the train was at the bottom of the lift and didn’t engage with the tyres somehow and rolled back.

    2 separate people have acknowledged it happening and I can’t see any benefit of someone making it up. Maybe it did happen but just not as violently as they’ve described? Could they have just reversed the drive tyres to bring the car back to the station?

    Exactly, it was probably a bit of a shock and jolty but probs nothing worth media coverage. Hopefully back open tomorrow.

    This account is slightly different. Perhaps Chinese whispers have overblown the matter.

    Gosh, that report makes it sound worse than the last one did…

    It does make me wonder, though, why none of the media got a hold of this story…

    Might be wise we all sit tight and wait. Speculating a large incident might not be the wisest idea.

    Certainly a very interesting development if true - I always thought the lift drive tyres stopped once the train had passed over them? Always assumed it was an anti-roll back feature?

    Hopefully nobody was seriously hurt, guess we'll sit tight and see if the Resort make comment.


    EDIT
    Yeah this video (at the bottom of the frame), does show the drive tyres stopping once the train has passed.

    The online coaster nerd community has thrived on this stuff for 20 odd years.

    The anti rollback is built into the motors so they can’t go the wrong way but of course if it’s all wet it can happen.

    I never thought of that actually, makes sense though!
    Not failsafe like rack and ratchet systems on chain lifts though, like we said.
