초록
Running resistance is essential to design a traction and braking forces of a train. the basic elements on the running resistance and measurement methods are reviewed. From measuring data with coasting energy method, the effects of the environmental condition (eg. wind) and measuring error are analyzed. In a tunnel, running resistance is higher than that of open field about 10 % and, it has almost half scatter width mainly due to external wind.
