What does the term "interlockings" refer to in train control?

The term "interlockings" refers specifically to a system that controls train movements through junctions and crossings. This system ensures that tracks and signals are properly coordinated to prevent conflicting train movements, which is crucial for maintaining safety and efficiency on the rail network. Each interlocking system manages the routes that trains can take and manages signals to ensure that only one train can occupy a specific track section at any given time.

By connecting various switches and signals, interlockings play a critical role in ensuring that trains can navigate complex train networks safely. This coordination reduces the risk of accidents and allows for smoother transitions between different tracks, particularly at busy junctions where multiple routes converge. Understanding interlockings is essential for conductors and other rail personnel, as it highlights the importance of secure and systematic train operations.
