Two tracks make for a front and back guide. That way they can alter the direction the boat points by separating the 2 channels. Notice the right hand channel ends sooner in the shed than the left hand channel.So this picture confuses me. Obviously this is a backstage maintenance bay area, but is that one or two tracks? I think it's one track with a gap on each side. But maybe it's actually two tracks, one to send the boats in from the ride and one to send them back out. The boats do look pretty small in the concept art so it's possible that two tracks could fit there. I really don't know and can't tell from what we've seen, does anyone else have an idea?
