I don't think I realized Vekoma was building both rides. Would certainly make sense that if the track pieces were similar it would cut fabricating costs to build them all at one time.
As much as we see this over and over again, I am still amazed at how well Disney 'hides' large buildings that house the workings of the attractions we enjoy so much. The Ratatouille building is a fair size, yet walking through World Showcase it's practically invisible!
