What defines a Block Limit?

A Block Limit is defined as a signal that indicates a limit for block occupancy. This means that the Block Limit serves as a critical reference point on the railway track, informing train operators about the boundaries within which only certain trains can operate at a given time. It is essential for maintaining safety and efficiency in rail operations by preventing multiple trains from occupying the same section of track, thereby mitigating the risk of accidents.

The function of Block Limits ensures that trains know when to stop or proceed based on the signal they receive, which helps in regulating train movements throughout the network. In essence, these signals play a vital role in traffic control on railways, ensuring that trains are spaced appropriately to avoid collisions.

Understanding the role of Block Limits is crucial for anyone involved in railway operations, as it forms a foundational concept in train scheduling and dispatching practices.
