The purpose of this article is to empirically suggest the necessity of reconsidering the new aptitude factors such as the ability to withstand work stress, to handle unusual events, and to work independently, in the respect that the environmental change in railway safety-critical worker's job should be flexibly reflected in the current aptitude management system. Besides, several ways of reducing the stress level for the railway safety-critical workers were suggested as well.
