  "term": "Track circuit",
  "field": "Industrial and trades",
  "definition": "An electrical circuit formed by the rails of a railway track, used to detect the presence of a train or railcar. When a train occupies a section of track, its wheels and axles shunt the circuit, changing its electrical properties. This change signals track occupancy to the interlocking system, preventing conflicting movements.",
