Railway accidents due to human error continue to increase, and developing technologies that reduce the risk of human errors made by drivers is a global issue. Korea Railroad Research Institute has developed a virtual engineering-based railroad driver cab ergonomics verification simulator for international standards. The simulator’s capability has been expanded to jointly train and evaluate integrated Non-Technical Skills (NTS) of drivers, controllers and signallers, such as information exchange and communication in accident/abnormal/emergency situations, to improve railroad staffs’ safety duty capabilities. This paper describes the results of the simulator and our findings.
