The best thing to do would be to watch this video all about X:\ No Way Out which was produced in 1996 by Thorpe Park when the ride was about to open: X:\ Promo video
There was never a fire in the X:\ No Way Out building. The fire at Thorpe Park was in 2000 and affected two other rides. The queue line was shortened for maintenance reasons and to free up the space to be used for Fright Night Mazes in 2002.
The full length of the queue line had sound effects and each ride train had an on board sound system with two speakers on each car.
