Abstract: In order to improve the safety quality of railway workers, a safety emergency practival drill system was established based on 3D-tech with analysis into its connotation, composition and current situations. The overall purpose, framework, component modules and technology realization routes of the system were illustrated, and the feasibility of the system were further explained in accordance with practical cases, i.e., constructing emergenchandling exercise scene for abnormal railway transportation built by 3D simulation technology to provide the opportunity for the railway workers to control the whole emergency handling process under the circumstances of human-machine-interface. With all those functions, the system allows the railway workers to fully experience the real working scenario, and therefore master the safety knowledge and operation skills of emergency handling more efficiently, to reach the point of improving safety quality. The results show that 3D practical training system integrating teaching, practical training and evaluation functions solves the problems of normal training well while avoiding the deficiencies of on-site simulation, simulation practical training, virtual exercise and other training methods.

Key words: 3D, emergency drill, railway workers, safety quality, improving
