What happened to the Arrow Stand-up?

I was reading the latest issue of "Rollercoaster!" magazine, and they had an article on the corksrew's anniversary. They had a picture of an Arrow Dynamics stand-up coaster going through a corkscrew at Worlds of Fun (not sure if that's the park or not). I think it said that they took the trains off of the coaster and just put normal looping coaster trains. Why did this park do that? It looked like it would've been cool to see Arrow Dynamics build more of these. Has anyone ridden this coaster when it had stand-up trains? Also are they going to build anymore like that?

P.S. Are there anymore photos of this coaster when it was a stand-up coaster?

It was probably shut down because of the Horsecollar ;).

Wel, it was an arrow looper at first, then WoF xperimented and put stand-up trains on it, but it sucked, so they removed it...

Was this on Orient Express?

No, it was something like Extreme Roller, or sumthin. It's in the history on the site, but I'm too lazy to check.
