Visited DMP with a friend yesterday, had an absolutely fantastic time ( :D ), and got on all the important rides more than once. In fact, we were probably pretty much done by 14:30ish - it was surprisingly un-busy.
We rode Ben 10 a couple of times, (and thoroughly enjoyed it), but oh boy was it experiencing issues...
From the start, it opened around 30 minutes late. When walking past it at one point, we noticed maintenance poking around under the platform near the front of the station.
When we noticed it testing around 11am, we joined the back of the (shortish) queue, and were soon let into the main queue (in which the effects were all switched off. Soon rectified, though, and we watched the interactive displays light up to show the Windows XP boot screen :P). Nice to see that the wooden panels which create the queue have now been painted.
Once we got near the front, it was clear that there were issues. Each dispatch was accompanied by a horrendous mechanical screaming noise, which was clearly a problem with the dropping floor. I managed to record it on AudioBoo, here
(which strangely enough doesn't seem to work in my copy of Chrome... works fine in IE, though...).
Looking carefully at the floor, it was clear to see that it was not at all level. Towards each end of the station, the moving floor sagged below the fixed floor by a centimetre or two, whilst towards the centre it bulged above by about the same amount.
On a few occasions, the train would return to the station, but then the restraints would fail to release, leaving riders stuck for up to 5 minutes. To rectify this, the ops opened and closed the air gates, started lowering the floor but quickly reversed and raised it. This seemed to work, which suggests that there's definitely a problem with the positioning of that floor.
After opening late, there was a period of about two hours later that day when the ride was closed again.
Clearly the floor is the problem here. I do wonder a little why the floor needs to lower at all - once the train has returned to the lift hill and is released to return to the station, the floor starts raising before the train has stopped, so there must be enough clearance with it in place. If not, then surely enough clearance could be achieved just by making the platform a little narrower, say 5cm each side, which wouldn't impact much on the accessibility of the train.
Any which way, this problem needs addressing...
