Indusi, officially "Punktförmige Zugbeeinflussung" is a cab signalling and train protection system used in Germany, Austria, Slovenia, Croatia, Romania and Israel. The magnets generate a magnetic field in a specific frequency. A trainboard receiver relays the signal to the train's onboard systems, which can force the train to a halt.
