Final answer:
The question is asking for a clarification of the duties of trackmen as outlined by a specific item in a document, likely a job description. The reference '5-169' could point to a clause or item number specifying certain responsibilities within that document.
Step-by-step explanation:
The question appears to pertain to the responsibilities and roles of trackmen. Since the duties statement is referenced, it is likely that the question is asking for a clarification or an explanation of specific items listed in a job description or role obligations document. Trackmen typically work on railways, maintaining and repairing the tracks to ensure the safe passage of trains. Their duties may include inspecting tracks for defects, replacing worn or damaged rails, and performing general maintenance work to keep the tracks in good condition.
Without the full duties statement, we cannot give a specific answer to what '5-169' refers to, but in the context of job duties for trackmen, it might indicate a particular clause or item number in a document detailing their roles and responsibilities.
