Considering the linkage of the information about the railway car that is currently operated and the necessity of continuous information transmission, the research was carried out considering the development of the technology for improving the performance of existing devices. Information on the current trains is provided to the ground operator on a limited basis for some important information. It has not been possible to convey a lot of information to the ground operator because the communication status and information transmission ability and security may be troublesome to transmit a lot of information known to an engineer or a train to a ground operator. TSMD(Train Safety Monitoring Device) is possible to expect the effect of securing the safety of the operation of the train and improving the operation efficiency because it is transmitted to the ground operator in real time. This paper reviews the research results of the LTE data transmission quality measurement test of the real-time transmission device of train condition information.
