If they could computer program the gates to open as soon as the coaster stops in the loading station, or just train the operators to do so, it wouldn't be a bad idea. I think the gates are a safer way to go. There certainly are a lot of air heads out there, and it would make the operators lives easier, I'm sure. All I hear once I get in the stations are, "Please keep your feet behind the yellow line," about a hundred times. Stick gates in there and they can concentrate more on saying, "Please do not sit or stand on the rails!"
