HBD(Hot Box Detector) is a device to monitor temperature rises to inappropriate lubricant use or mechanical defects. If a train operates without recognizing such an effect, it might result in bearing overheating due to defects and cause a dangerous situation that it could derail a train owing to the damage of axles. Now for the Gyeongbu HSL at 300km/h, the laws related to monitoring overheated axle bearings are notified in the Railway Safety Law and the Railway Construction Law. But in case of the conventional speed-up lines that a train operates at 180 to 230 km/h, the revised bill of relevant standards is ongoing. Therefore in this paper we present references and reviews investigated in order to use the optimal HBD in the conventional speed-up lines.
