I just captured the video from yesterday of the trouble with S:UF at SF:gadv. They were running 1 train all day, At around 6 pm, They transfered another train on. As it was making its first run, this is what happened.
As the train was coming in to the twist right before the brakes, It made 2 loud bangs...Shortly after, It lost a pretty big piece from what looked like to be the wheel assembly. It sounded pretty scary standing near it, 3 times as loud as it is on camera. The people in the line all turned around right away. Anyway, Here is the link to the clip...
All i know so far is that it came from the 4th car. Thats where to object appeared from. That is the area that the engineers were looking at before they transfered the train back into the storage building.
I had thought that too about it being a tool. But you would think if there was a loose wrench it would have fell off the train during the Pretzel loop or any of the other series of turns before the inline twist.
The first bang sounds like it came from that piece hitting the track and the second bang looked like it came from the piece hitting a support. *** Edited 6/10/2004 9:19:11 PM UTC by CoasterDude316***
Ya. Its a wheel from the fourth car. left side, seems to be the the track wheel. I watched the video frame by frame and traced the wheel back to the car. It flew off and looks like it hit the next support (the louder bang) and then flew back a bit and landed on the ground.
