Kalymbet M. V. Development of new resource-saving and environmentally friendly technologies for the operation of railway transport. – Qualifying scientific work as a manuscript. Dissertation for the Doctor of Philosophy degree in specialty 275 – Transport technologies (by types). State University of Science and Technology of Ukraine, Dnipro, 2023. The dissertation work is devoted to increasing the efficiency of the subjects of the transportation of dangerous goods (DG) and the safety of the operation of railway transport in case of emergency situations during their transportation, as well as the localization and liquidation of their emergency spills. The efficiency of the work of all subjects of the transportation of dangerous goods is characterized by the coordinated work of all participants in the "sender-carrier-recipient" system. Strict compliance with the transportation procedure (Requirements, rules, regulations and maintenance of the DG), which is regulated by the Ministry of Infrastructure, will prevent the occurrence of an emergency situation during the transportation of dangerous goods by rail transport. Professional maintenance and support of DG by full-time employees for all participants of the "sender-carrier-recipient" system, which has the appropriate certificates, allows not only to prevent the occurrence of an emergency situation, but also to immediately start localization and liquidation measures to eliminate the consequences of an emergency spill of a hazardous cargo emission. To date, there are several problems regarding the training of certified specialists with the cooperation of Special Training Centers and joint stock company "Ukrzaliznytsia": - lack of motivation in successful training among infrastructure workers; - a complex schedule of working hours and a tight schedule of special training; - low staffing, associated with a difficult economic situation; - insufficient level of education by profession; - non-compliance of the student with age requirements (training of workers of pre-retirement and retirement age); - lack of provision of special training places with the appropriate number of regulatory documents and manuals, in particular in the case of special training on lines; - imperfect personnel due to low wages; - an imperfect procedure for selecting employees for special training. Another problem is the morally outdated equipment for carrying out emergency reconstruction, localization and liquidation works. From available sources it is known that the main production assets of joint stock company "Ukrzaliznytsia" are worn out by more than 90%, in particular, this applies to emergency and repair and fire trains and parts that work on them. In fact, you have to work on outdated equipment. Therefore, the question arises of developing means and methods of localization and liquidation of the consequences of accidental spills of hazardous substances (HS) using innovative materials and logistical solutions The following objects of research are considered in the work: the process of transportation of dangerous goods (DG) taking into account the risks of emergency situations that pose a threat to human life and the environment. Keywords: transport systems and technologies, improvement of operational safety, expert assessment, system analysis, risk indicator, system “sender – carrier – recipient”, restoration of trains capacity, environmental technologies, dangerous goods, accident localization, accident elimination, carbonization, universal sorption shet, dynamic characteristics of the hopper wagon.
