Abstract (en)
A monitoring system includes a pressure detection means for detecting a pressure inside a retainer, and a failure sign determination means for determining whether there is a sign of failure of a foreign substance removal device based on the detected pressure inside the retainer. The pressure detection means is disposed in the foreign substance removal device including a generator that generates compressed air, the retainer that retains the generated compressed air therein, and a jetting device that jets the retained compressed air to blow off a foreign substance existing in a diverging portion of a railway track.
