Webslave, Ads DID say if it is shown maintenance was followed, then it would fall on the manufacturer.
Wow - they must have woken him up in the middle of the night to talk about that. Has anyone looked on TPR to see if there is a similar discussion going on?
I must say i'm amazed this thread hit 128 posts in a mere 20 hours. That's got to be a parkz record.
I heard about this yesterday, but didn't go searching for info. I knew there'd be stuff on parkz when i logged on... I just didn't expect 6 pages!
My first thoughts on seeing the wheel on 7 news (the one on the upper evac walkway, not the one on the grass) was the rear wheel assembly had failed. I wasn't aware the front assembly had also failed (and presumably was the cause of the rear failure by the looks of things). With both left wheel assemblies compromised, it's a miracle the whole train didn't cant over on it's right side, especially with the inertial forces experienced in the previous turn.
I'm thinking the front assembly wasn't totally affected, and by the looks of things, the front assembly is what kept them all on the track. I'm assuming the articulated joint between front and back has a limit, and the angle of the rear car off the track is probably at that limit.
I join others in the praise of the park and it's staff for quick action. QFRS for their rescue efforts, and join in support of the maintenance team who whether or not they did the best job they could (which I have no doubt they did) will all probably be feeling pretty crappy right now - some of them are possibly also feeling responsible and it wouldn't hurt VRTP to have a counsellor on site for a few days to let the guys talk their feelings out.
Sure nobody was injured (thankfully) but they'll all be feeling responsibility regardless. They'll also be paranoid about anything else they work on until the cause of the failure is proven.
There have been failures in AUS as a result of maintenance (space probe cable snap), but with such a new ride, i'm hoping this is manufacturing, or poor quality spare part rather than maintenance. I've got faith in the VRTP maintenance team that I hope is well founded. As others have suggested - the unique train design for GL is possibly at fault here... but we'll have to wait and see.
