How must the limits of Form D be designated in DCS territory?

In DCS (Dispatcher Controlled System) territory, the limits of Form D must be designated by station names or whole mile post numbers. This method of designation ensures clarity and accuracy in defining the boundaries of the authority granted by the Form D, which is crucial for safe and efficient train operations.

Using station names provides a clear point of reference that operators and dispatchers can easily recognize, while whole mile post numbers establish specific locations along the rail line that can be verified against physical markers. This level of specificity reduces the potential for misunderstanding that could arise if more ambiguous designators, such as street names or general landmark features, were used.

Employing precise designations helps maintain operational integrity and enhances safety by ensuring that all personnel are aware of the exact limits of the authority and can act accordingly within those confines.
