Since opening the Seoul-Busan High Speed Railway of the Seoul-Deagu line in April 2004 and after Ho-nam High Speed Railway in April 2015, various of failure have occurred in the railway and it demands the causes of the failure and considers a countermeasure till lately. Korean high speed railway system has followed the French high speed railway system. After installed, there was an analysis about environment affects by the railway system in domestic, seasonal characteristics, maintenance and the schedule for the system and material supply state. Also stability has improved though analysing causes of the failure. By these, this paper has proposed the maintenance standard direction for various facilities and the goal is a maintenance efficiency.
There were diverse cases in the Seoul-Busan High Speed Railway while maintaining the whole system. To fix the cases, the new method has proposed. After analysing the wire structure in various facilities, blackets or holders that support the wires has worn down through train operation. However, this could not meet the facilities' reorganization time. But extra solution needs to be appear according to expand the train service and shorten the maintenance time. Especially automatic tension balancer, insulators, air joints, air sections and equalizer in tunnel have to work consciously. To establish countermeasures hereafter, research result that maintenance time should be shorten and facility improvement have to implement for safety train operation has derived.
