As a developing direction of the public mobile communication, LTE has become a consensus, and it also begins to study the evolution of the next generation mobile communication system for railways. LTE has been applied successfully in Shuo-Huang railway due to its high technical maturity and complete industrial chain of the mobile communication system. The study on LTE QoS is very important in railway engineering application. This paper discusses QoS index of the railway LTE system combining with the characteristics of railway wireless communication business, hopefully providing reference and guidance for the application and development of LTE - R.
