Interlocking systems

Interlocking systems are safety mechanisms used in railway signaling to ensure trains operate safely by preventing conflicting movements. They coordinate signals, switches, and other track equipment so that only safe, non-conflicting routes are set for trains. When one part of the system is active—like a switch being set to a specific track—other parts automatically adjust or lock to prevent dangerous situations, such as two trains colliding or being routed onto the same track simultaneously. Essentially, interlocking systems act as a secure control process that manages train routes and signals to maintain safe railway operations.
