So there is unconfirmed info from a few different people on reddit that says Twisted Timbers has been running much faster than expected causing the sensors on the break run to stop the train, creating much of the down time the ride has been having. Supposedly, the park tried using a different wheel combination which caused the train to valley that one morning a few weeks ago. I have heard about it running faster than expected for a little while now, but this is the first time I have seen someone mentioning it being an issue. Can anyone verify the accuracy of any of this?
