A improved train real-time tracing system based on distributed Fiber Bragg Grating sensors is introduced in this paper. Without delicate sensing head, the system can realize the real-time detection of the railway condition and trains' running behavior such as the position, velocity, acceleration, load on axle, number of the axles and so on. To some extent, the system can also implement warning of the train accidents. The system will be significant to the railroad transport.
