I don't those two rides (Bobs/Nights) but according to news reports there was "track" falling from the trailer, so I am guessing that the load was from either the Crazy Mouse, or one of the kiddie coasters, but you know news reports and it may not even have been actual "track".
That being said, hope they didn't trade in the Bob's at least, they have had that quite a while and just recently redid it I believe, or they still have all the equipment and just sent it somewhere else.
