In many subways and light rail trains, systems with inductive communication from the vehicle to the ground are used to keep track of where each train is.

At LSE we have developed an antenna unit to be mounted under the train, to be used in such systems where it works together with a loop antenna placed between the rails of the tracks.

These train antennas are designed to work in the rough train environments and are highly resistant to heat, cold, moisture and vibration.
