The 'defect detector' system refers to an automated system that monitors train components for malfunctions while the train is in motion. This technology plays a crucial role in ensuring safety and reliability in rail transport. As trains travel, the defect detector uses sensors and advanced diagnostics to assess the condition of various components such as wheels, bearings, and brakes. If any irregularities are detected, the system provides alerts to the train crew and the dispatching center, allowing for timely maintenance or intervention before a malfunction leads to a more serious incident.

In contrast to a manual inspection process performed by conductors, which is labor-intensive and may not catch every issue, the defect detector system provides continuous monitoring that enhances safety by quickly identifying potential problems. Its focus is not on emergencies related to broken trains, as that would fall outside its primary function, nor does it apply to any regulatory systems for passenger trains, which have different operational requirements and oversight mechanisms. Thus, the automated nature and real-time monitoring capabilities are what define the 'defect detector' system in the context of rail operations.
