What does "blocking" refer to in train operations?

Blocking in train operations refers to the practice of controlling train movements to ensure safety and prevent collisions or accidents. This involves strategically managing the flow and positioning of trains on the railroad tracks, often through signaling systems and communication among train crews and dispatchers. The goal is to maintain safe distances between trains, coordinate their movements, and manage traffic flow effectively on the rail network.

By utilizing blocking, train operators can minimize the risk of accidents and ensure that trains operate smoothly and safely in conjunction with one another. While scheduling trains and inspecting train cars for safety are important aspects of rail operations, they do not directly pertain to the management of train movements in the context of preventing collisions, which is the essence of blocking. The method of boarding and unloading passengers also falls outside the scope of this term, as it does not involve the operational safety aspects related to train movements.
