Introduction. JSC "Russian Railways" monitors morbidity and changes in the health status of employees, including after the use of high-tech assistance methods (radiofrequency ablation, joint replacement, etc.). In some cases, JSC "Russian Railways made decisions on individual admission to training work of persons who have undergone such high-tech interventions, even if there are medical contraindications to work. The study aims to learn the feasibility of individual admission to work of train personnel after high-tech medical care. Furthermore, it makes the professional longevity of railway transport workers. Materials and methods. We analyzed the information for 2015-2020 about the identified medical contraindications in workers directly related to training traffic and shunting work, with rhythm and conduction disorders, surgical diseases, and lesions of large joints, including those aimed at high-tech assistance. In addition, the researchers evaluated the clinical and economic efficiency of their admission to work. Results. More than 70% of employees after radiofrequency ablation and joint replacement can return to train workers, which has brought an indirect economic effect of at least 150 million rubles over six years. It is a prerequisite for the revision of existing regulatory documents. Conclusions: The use of high-tech treatment methods makes it possible to prolong professional longevity through individual admission to train employees of the group of machinists, drivers, and their assistants. The research showed an indirect economic effect for the railway industry for at least 150 million rubles over six years, which is the basis for changing medical expert approaches and medical contraindications to work directly related to training traffic.
