What must the neighboring dispatcher ensure when allowing movements at 241 permission?

In the context of railroad operations and dispatching, when allowing movements at 241 permission, it is essential that signals must be at Stop and blocks applied. This rule serves to ensure the safety of train movements in potentially conflicting or overlapping territories. By requiring signals to be in the Stop position, the neighboring dispatcher can confirm that trains are not in danger of encountering each other unexpectedly.

Having blocks applied means that that section of track is secured against unauthorized movements or accidents. It provides an additional layer of safety by ensuring that no trains are occupying that track even as the dispatcher allows movements under specific conditions. This is particularly crucial in managing and mitigating risks associated with train operations.

While accounting for all trains, ensuring signals are at Proceed, or revoking blocks may be considerations in other scenarios, the fundamental safety requirement for 241 permission dictates that trains can only move when signals are secure and blocks are in place to prevent accidents and ensure orderly operations.
