The purpose of this study was to analyze and improve the communication interferences in the wireless communication equipments of the CBTC applied to a model intelligence train control system. So far train positions have been traced by the conventional fixed blocking system to control the operation of the trains but the new CBTC system uses the on-ground location to transmit the train positions wirelessly to the ground control center continuously so being more vulnerable to communication interferences. Although the researcher analyzed and improved such interferences in the communication equipments of the CBTC system there remain more rooms for its improvement.

The maintenance of the turnout is composed of signal field and track field on business the electrical and mechanical field on system. adjustment and maintenance carry forward through coordination with these fields. In the case of turnout equipment used in a first phase of Seoul-Busan high-speed train it is treated by classifying as mechanical adjustments and electrical adjustments. Mechanical adjustment is conducted with focus on fine adjustment to meet maintenance standards limits(1mm or less) about interval of basic rail and tongue rail about each part of track transition equipment. This refers to mechanical adjustments performed mainly with physical changes and movement characteristics between basic rail and tongue rail by considering the overall environment surrounding track side of section installed track transition equipment. However these series of maintenance are conducted in state that high-speed train is not in the process from 1 am to 4 am at night but common workers for maintenance are not familiar with the operation and checking about various situation and the workers are even insufficient. Maintenance training using mixed reality is conducted in the place of business we tried to overcome several problems of safety and time reduction through this training.
