When freight trains are moving high/wides, what must the Dispatcher be informed about?

When freight trains are moving high/wides, it is crucial for the Dispatcher to be informed about the car number and position in the train. This information is essential for several reasons.

First, knowing the car number allows the Dispatcher to track the specific high/wide cars within the train, which is important for the safety and efficiency of train operations. High/wide loads often require special handling and monitoring as they can pose a clearance risk to structures and other trains on the same route.

Second, understanding the position of these cars within the train helps determine how they interact with the rest of the train and the environment, as the dynamics of a high/wide load can differ based on its location. For example, if the high/wide cars are positioned towards the front or rear of the train, it may affect how the train negotiates curves or passes through tunnels and overpasses.

The other options, while important in their own contexts, do not directly pertain to the immediate operational concerns regarding high/wide freight movement and ensuring safe passage along the route.
