What is the purpose of an absolute block in railway operations?

The purpose of an absolute block in railway operations is to establish a safe zone where no train is permitted to enter. This system is crucial for ensuring the safety of train movements, as it prevents collisions and provides clear sections of track that are reserved for individual train movements. By using absolute blocks, railway operators can effectively manage train traffic and maintain a systematic approach to scheduling and dispatching trains within a defined segment of the railway infrastructure. This safety measure is especially important in areas where multiple trains could otherwise be at risk of occupying the same track section simultaneously.
