That was back in the days where you had a handful of shows on the upper level and the Tram. You take the tram to the lower level where they let you out and do the special effects show. Then you got back on the tram and did more tour. Then you got off the tram and "rested" in Prop Plaza which was an area with giant props. Finally you got back on the tram and finished the tour. Afterwards, you did the four shows and then left. No rides. They even assigned you tram tour times when you enter the park so everyone doesn't hit the tram first.
I hear Prop Plaza is still there. They use it for private functions.
