What does everyone think of having Tron light cycle trains racing around the peoplemover track. You could use a Vekoma Booster Bike coaster track mounted just above existing peoplemover track. With vekoma booster bike trains outfitted as light cycles.These coasters typically use LIM to be propelled not a traditional lift hill. You could have LIM's placed throughout the track to increase speed. Plus if track is placed above peoplemover track you could bank the turns to keep the thrill of the ride without slowing down( obvious retrofitting of support coulms would need to take place). In the tunnels you could use Projections and lighting effects from Tron since space in these areas is very limited.(imagine opposing light cycles projected digitally on screen racing and battling you throughout the course of the ride.).
