I agree SROS221! I was at SFNE once last year when the line was out of the queues, past the fountain, and working its way up the ramp out of the Superhero Adventures area, and SFNE was running one train on Superman. The red train was just sitting on the transfer track. No maintenence people were seen working on it all day. I guess I can't know for sure if they really did have a good reason to only be running one train, but knowing SFNE, I have my doubts. Even when they are running two, the one train always gets back and is halted on the break run for around 30 seconds (longer than Mantis got stacked for with 3 trains! :)) To me there is no excuse why the second train can't be starting up the lift as the first one hits the breaks. That is probably around 2 minutes!

P.S. Everytime I go there to ride S:ROS, I ask myself, "Why does such a great ride have to be here?"
