The influence of the safety system of the "Afrosiyob" high-speed electric train on operating conditions
Objective: To determine the impact of the security system during movement on the operation of the high-speed “Afrosiyob” electric train, which is an analogue of the Spanish Talgo-250 electric train. To analyze driving modes and operating conditions taking into account the increased safety requirements in relation to the organization of movement and operation of the high-speed electric train at the Tashkent-Samarkand section of the Uzbekistan railways. To assess the risks and threats to security in terms of the severity of their consequences and negative impacts, as well as their repetition or likelihood of causing a safety hazard. Methods: The safety system of the high-speed electric rolling stock was analyzed and a series of traction calculations were performed at the Tashkent-Havast section with the introduction of restrictions on trafﬁc modes due to the protective effects of the security system. Results: The conditions and parameters of the high-speed rolling stock operation were considered taking into account the requirements for ensuring safety in case of travel time restrictions. Practical importance: The conducted study is useful for railway transport engineers, in particular the specialists whose work is connected with the organization of movement and operation, as well as the development of measures to improve the efﬁciency of using the high-speed passenger electric rolling stock at the main and suburban railway sections of Uzbekistan.
