The safe operation of Chinese Train Control System Level 3 (CTCS-3) is of great significance, particularly with respect to the increasing operational speed and expanding railway networks of the Chinese high-speed railway system, which has drawn deep concern from both customers and strategic makers. A hazard and operability (HAZOP) study has been recognized as an effective systematic examination to identify any potential problems existing in various industrial processes or operations. This paper presents a process of applying a HAZOP study to identify the hazards of a CTCS-3 onboard system for the first time, which is composed of two major parts: system models and hazard identification on the examination session. To better reflect the structure and functions of a CTCS-3 onboard system, the following models are developed, i.e., a reference model, a function hierarchical model, a state diagram, and a sequence diagram. To demonstrate the effectiveness of the HAZOP study, hazard identification on the basis of the functions of the CTCS-3 onboard system and a scenario of temporary speed restriction is considered and employed. The results indicate that existing hazards can be dug out at express speed, which allows the relevant actions to be proposed and implemented to prevent the hazards from spreading to a wide range in the whole CTCS-3 onboard system. Index Terms-Chinese Train Control System Level 3 (CTCS-3)onboard system, hazard and operability (HAZOP) study, hazard identification, unified modeling language (UML) model.

The Hyperloop system is a novel conceptual system aimed to provide a high speed public transportation service in the future, featured with a reduced-pressure tube in which pressurized capsules ride on a cushion of air that is driven by a combination of linear induction motors and air compressors. The project of developing Hyperloop is based on the crowdfunding-sourcing mode, which is dramatically different to the traditional way. Identifying the hazard of the Hyperloop system would be helpful to the publics' acceptance of the safety from the concept stage. If all the hazards were dealt properly, Hyperloop could be more realizable than ever. From system safety research's point, it is definitely a good opportunity to carry out different safety analysis and hazard identification methods to verify the effectiveness. With the predefined method of the model based HAZOP, a team work to identify the hazards of the Hyperloop system is carried out to verify the effectiveness.
