Since the KTX starts operation in 2004, Korean railway system has sustained the highest safety and accuracy. In order to keep this achievement, the LTE based wireless communication system has been introduced for mobile communications and signal transmission. railway, and activities for its standardization are on the way. Railway communication system will be used as part of national safety net through interworking with safety network. This paper reviews the contents of standards and technologies in an LTE-based railway communication(LTE-R) system, and the items to be standardized to improve operational efficiency of the railway system by building a national railway radio communication system.
