The reliable detection of trains in intelligent transportation systems is very important for a safe circulation. The system proposed makes the detection with a sensor located next to the railway, without additional electronics in this place. All the electronic process equipment is concentrated in a point that can be far away the rail. Moreover, the system is capable to detect the sense of circulation. Several sensors can be connected to the process equipment with only two wires. In order to compensate the attenuation and external noise, a signal coded with Golay complementary sequences is used.
