What is a "train order"?

A "train order" is a written directive from a dispatcher that provides instructions to train crews regarding the movement of trains. This could include information such as authorized speed limits, directions for maintaining safe distances between trains, and changes to scheduled routes or stops. When issued, train orders are crucial for ensuring safety and efficiency in train operations, helping to prevent accidents and facilitate smooth coordination between different trains on the same track.

While other options such as a method for scheduling repair work or a manual for train operation might pertain to aspects of railroad operations, they do not capture the specific function of a train order. Communication between conductors is indeed important, but train orders specifically refer to the formal instructions issued by a dispatcher, distinguishing them as an essential element of railway management and safety.
