The reliable detection of the passage of railway units by certain points of the railway line is very important for a safe circulation. Thus the system proposed in this work makes the detection with the sensor located next to the railway, without additional electronics in this place. All theelectronic process equipment is concentrated in a point that can be far away the rail. Moreover, the proposed sensor is capable to detect the sense of circulation. In order to compensate the attenuation in wires and the external noise, we use a signal codified with Golay complementary sequences.
