What is the role of the block operator according to Rule 316?

The role of the block operator, as defined by Rule 316, is specifically to authorize movement through block-limit stations. This responsibility is crucial for maintaining safety and efficient operations on the railroad. The block operator ensures that only authorized train movements take place, which helps to prevent collisions and ensures that trains are properly routed.

In the context of railroad operations, block-limit stations serve as critical points where the authority to operate a train in a specific section of track is granted. The block operator plays a key role in this process, as their authorization indicates that the track is clear and safe for a train to proceed. This function is vital in ensuring that all train movements are conducted under the established rules and procedures, thereby facilitating safe and coordinated operations on the railway.

Other options, such as issuing schedules for trains, performing maintenance on signals, or resolving disputes between train crews, do not fall within the specific responsibilities attributed to the block operator as per Rule 316.
