Industrial railway safety depends on three general types of interlocking systems: mechanical systems, electrical systems that include relays and electro-mechanical components, and electronic/computing-based solutions.

5 / 8

Lawful operations at most Indian railway stations depend on Panel Interlocking (PI), which uses single switches to manage signals and track points. Larger stations that handle intense train flow implement Route Relay Interlocking systems as their main interlocking method. The two-button operation of this system enables users to set complete train routes.

Interlocking continues to play an essential role because it establishes safety measures minimizes human mistakes and enhances operational performance.

7 / 8

Industrial interlocking systems contribute to safety standards through their dual functions of reducing risks and stopping unauthorized personnel while maintaining operational security.
