Shenzhen Happy Valley ordered to close after roller coaster train collision

This is pretty much the nightmare scenario for launched coasters that don't rely on LSM's to naturally slow them down. I didn't realize that there were any pneumatic S&S launchers still operating.

What are the anti-rollback mechanisms on these S&S launchers? Is it the same as Maxx Force

Edit: from a quick scan of Maxx Force YouTube videos, it looks like fins, presumably some conductor, pop up behind the train as it climbs the first element similar to any Intamin hydraulic launch.

I think there’s something to be said for sitting an extra 30 seconds on the brakes ahead of the station until the previous train is over the lift and well out of the way. A common complaint amongst enthusiasts is stacking or really, any perceived waste of precious park time.
Now, I don’t know this particular ride or how much space is between the station and the lift, but more’s the better as far as I’m concerned. Lift accidents happen all too often.

It's not a lift, it's just a pneumatic launch track.

Oh. So it failed a hill and fell backwards? I’m going to have to look into this further I guess.

It looks to be like a rollback no different than after a launch on Dragster 1.0 or Maverick. However, there was nothing stopping the train from just continuing full speed until it front ended the train in the station.

I asked a couple years back whether these types of systems would be considered fail safe (was asking about Dragster, but relevant to this ride too), and people responded there's nothing to worry about. :)

With that said, gross negligence on the part of the park isn't out of the question at this point.

Did Maxx Force operate this past weekend?

According to queue-times.com, yes. Maxx Force was open Saturday, Sunday, and Monday.
