runaway train

oh boy looks like a third runaway train has happened on my list but this one is different this one is a steel works train and for some reason the driver went to go have his lunch break and accidentally left the throttle forward and the train is now moving by itself and somehow nobody can stop it from the outside they can try and cut the power but it's a diesel train and there's nothing anybody can do about it not unless the train can be stopped from the inside will you be able to stop it what will you say what will you do
