Final answer:
The question pertains to an assistant station supervisor's responsibility to handle service diversion notices, likely within an organizational structure. The reference to (6-187) could be a form or part of a procedural manual, which would define the exact steps to be taken after signing receipt of these notices.
Step-by-step explanation:
The student is asking about a procedural element regarding service diversion notices in the context of an organizational process, probably within a corporate or a public transportation environment. When an assistant station supervisor receives service diversion notices and signs a receipt, there is an expectation that they must handle and perhaps file or return documentation. The specific form or document referenced, (6-187), seems to be a part of said procedure. Without additional context, such as the specific organization's protocol or whether (6-187) refers to a form or a clause within a procedure manual, it's impossible to provide a definitive answer.
However, typically, upon signing for the receipt of such documents, the assistant station supervisor would be expected to follow organization-specific guidelines for distributing the notices to relevant parties or entering the information into a tracking system.
