At the end of the season last year I got chatting to one of the engineers about stripping the trains down and asked him why the third train was never used last year. He said the plan was to never use the train but use it for spares and plans for using the third train required modifications done to the second lift hill. At the end of the day if a ride isn't safe to open its not gonna open! I'm sure Chessington are doing all they can to reopen the ride as fast as they can. After all there probably losing money on the amount of free tickets there giving out...
