Since Paramount has two other TOGO standups, could the trains be going to Toronto or Richmond as parts?? Unfortunately, I also think that the rest of KC could be joining SFGAm's Shockwave in the innerworkings of a steel mill.
I believe the King Cobra was the first SUCCESSFUL LOOPING standup in North America. World's of Fun put standup trains on their Arrow Corkscrew model ride called Screamroller in the 1983 season. It turned out to be a not-so-good idea since the ride was never designed to have standup trains.
If you are ever World's of Fun these days, you may get a wee bit confused on the Timber Wolf station. Because that station was originally designed for an Arrow looping coaster ;).
As for King Cobra... I really think we won't see this ride in operation again and I for one will miss it. If my memory serves me right, Sky Rider at PCW is the closest that I can get to King Cobra.
According to RCDB Rail Blazer at SF St.L added stand up trains in 1984, the same year that King Cobra was built and opened to the public. So now the true question is which one in america opened first with stand up trains? At least KC was the first designed as a stand up in America.
