The invention relates to a train obstacle information display method and device. The method allows a train attendant to obtain the operating state of an on-board obstacle detection system in real time and informs the train attendant immediately when an obstacle disturbing train operation appears, such that the train attendant walks to the head of a train to handle a traffic interruption accident caused by the obstacle; and when reaching the head of the train, the train attendant handles the accident according to an approach suggested by a handheld mobile terminal. Compared with the prior art, the invention can display obstacle information to train attendants on metro lines in a DTO mode and a UTO mode.
