Abstract
A series of research was carried out to clarify the relationship between visual display and the characteristics of eye movement of the railroad train drivers while driving. The features of their eye movement under the driving conditions are investigated with eye mark camera to investigate similarity and difference of the two different visual displays, i. e. presnt type adopted and the improved type. Main results obtained from the research are as follows; (1) Main task of train driver is to observe on forward of train. Ratio of forward was accounted for 75 percent to all observing time while driving. (2) Almost of all eye movements for train drivers on front panel displays have relevance to control speed of train while running. (3) Time needed to gaze upon the railway time table is clearly longer compared to that of the other meters of displays. (4) All meters on the display have tight connection with the watch in terms of visual pattern of drivers to keep train operating accurately.
