Vibration and acoustic radiation characteristics of rails are the keys for wheel-rail noises. In order to find out it, build a CHN60 rail three-dimensional finite element model and boundary element model in this paper and then do modal、harmonic response and sound radiation analysis for it. The results show that there are lateral、vertical and tensional three vibration forms in rail; the main vibration parts of the rail is the rail web and the both sides of the rail bottom ; there are multiple peaks in rails sound radiation curve in 0-4000Hz band, respectively, the sound pressure level is 82.1 dB (A) when the rail vibration frequency is at 625 Hz, 85.7 dB (A) at 2350Hz, 84.6 dB (A) at 4000Hz.
