In order to share train safety information when trains pass through long tunnels, steep curves and single tracks, it is important to develop a real-time two-way auxiliary communications system. This study would examine the possibility of the rail tracks as the transmission lines of PLC (Power Line Communication). Moreover, the data transmission characteristics of rail track PLC by distance were evaluated. Sustainable channel transmissions were 12 to 20 MHz and 25 to 33 MHz. Furthermore, experimental results showed that the signal attenuation at each frequency of 5, 10, 15, and 20 MHz is constant within 5%. This result shows that PLC, when using 50 m of rail track, can be applied commercially within the signal attenuation threshold of -70 dBm.
