My god yesterday we were in the line for the front and it rolled back two times and thay kept on doing test runs, and its the test runs witch I don't get cos whats the point of sending cars around with no people on because a roll back is not a fault,after its rolled back why don't thay just pull the train back and lunch instead of all that time of unload,pull the bars down,test,pull the 2nd trains bars down,test,pull the 1st trian's bars up and at LAST onload the people that have rolled back?
