Digging deeper into the Superman accident

I can't get it to work either. I tried pasting the link into a new window.

If you're getting the Angelfire logo, copy the link, then empty your browser cache, then paste the link into your location bar. That should work. At least it worked for me.

That worked, thanks. Now that this is resolved, we can turn our attention to SFNE's new coaster for 2002.

Just looking at that picture leads me to believe that simply cutting the air supply wouldn't cause a failure. I have a difficult time accepting that a simple counterweight system would fail. Perhaps the failure of the air system somehow damaged the valve that allows the air to vent.

Great report. One thing though, SROS at SFA only ran one train after the accident

Yo've got to give SFNE credit for the modifications to the rides primary, and especially the back-up, safety systems.  Sounds to me that it exceptionally unlikely that we'll see a repeat of this incident on any of Intamin's coasters.  Bad news is that it took an accident for them to realize that air hoses need to be SECURE for them to provide reliable air pressure, and that redundant safety systems must be installed to be useful.  Good news is that the accident involved no SERIOUS injuries. 

Hey this was in the Boston Globe yesterday. Guess the local press can still panic.

AGAWAM Superman coaster shuts down again

The Superman Ride of Steel roller coaster at Six Flags New England automatically shut down last weekend after computers detected a malfunction. The ride had just reopened after being closed for two weeks following an Aug. 6 accident that injured 22 people. An internal investigation by the Agawam amusement park found that the accident was caused by a faulty braking system. The weekend shutdown occurred around 10 p.m. Saturday after a computer read that ''something wasn't operating correctly,'' said Mary Ann Stebbins, park spokeswoman. The ride was closed for the night, but after safety engineers examined it, the ride reopened Sunday, she said.

so can we expect this to happen with MF at CP too?

Dave,

You mentioned that the drive tire would be too weak to pull the train out of the brake (that's why they designed them to swing out to let the train go). How impractical would it have been to use a small horizontal lift chain there? Would the load be similar to hauling the train up an incline?

Just thought it would be safer than allowing the brake to ever swing out.
