The human factor is known as the most important factor in rail accidents in Iran and some leading countries, and the shunters play a role in accidents among other human factors. Risk-taking is an inherent part of shunters' work as they engage in complex operations that require coordination between personnel, equipment, and the environment. This risk-taking can be affected by cognitive functions and personality traits. In order to better understand the complexity of factors affecting the risk-taking of shunters, mediating variables of self-control and social interaction can be helpful. The main goal of this research is to investigate the mediating role of social interaction and self-control variables in the relationship between cognitive functions (focused attention, sustained attention, situational awareness, planning and working memory) and personality traits (extraversion, emotionality and adventurousness) with the risk-taking of railway shunters. Questionnaires were used to measure risk-taking, social interaction and self-control, and psychological computer tests of Schuhfried Company (Vienna test system) were used for cognitive functions and personality traits. The statistical sample consisted of 165 shunters and lead shunters from Tehran and Isfahan districts. Finally, the structural equation model was used to investigate the relationship between variables using Smart PLS3 software. The results showed that social interactions in relation to cognitive functions (focused attention, sustained attention, situational awareness, planning and working memory) and personality traits (extraversion, emotionality and adventurousness), as a mediator, play an important role in the risk-taking of shunters but in examining the role of self-control, it was observed that this variable does not play an effective role as a mediator. In general, the findings of this research can be applied in the direction of recruitment, performance eva‎luation, designing competency systems, and enhancing employees in cognitive functions such as sustained attention, focused attention, working memory, situational awareness, planning and, personality, social interaction, and risk-taking in the railways. Moreover, this research can serve as a starting point and a small step towards larger initiatives aimed at providing better conditions for employees in this field in the future.
