I can confirm this more for you, It was confirmed at the ECC trip to Chessie on 24th February as well. Apparently Vekoma will be involved in doing all or most of the work to the coaster, apparently the coaster will receive New Trains, New Track and a New Control system + other small improvements to the coaster, all this will happen in the 2001 season and will definatly re-open in 2002. As you can guess, 2002 will be a big year for the Tussards Parks.
