How does the dispatcher stop the train if someone leans on it after they have given the nod?Because if the method of dispatch at a specific location has been agreed as being by dispatcher then that process needs to be followed. A dispatcher needs to monitor not only the platform/train interface as the doors are closed and the train begins to move, but also the passage of the train along the full length of the platform until it is no longer in the station. Clearly this cannot be done from within the train.
