Form D line 4, Form D line 5, and Foul Time may be issued only to employees who are:

• A. Qualified on the operating rules and the physical characteristics of the territory involved.
• B. Experienced in dispatching trains.
• C. Supervisors of the yard.
• D. Certified locomotive engineers.

Answer: (A)

The main idea is that disciplinary actions like Form D and references to line qualifications are limited to employees who truly understand the applicable rules and the specific territory where the incident occurred. If someone is not qualified on the operating rules and the physical characteristics of that territory, they may not fairly or accurately apply the rules or assess the situation, which could lead to misinterpretation or unfair penalties. This requirement ensures the person issuing the Form D and any related foul time is fully aware of what the rules demand in that area and how the territory operates, making the action meaningful and justified.

The other options don’t fit because being experienced in dispatching, supervising a yard, or being a certified locomotive engineer does not by itself guarantee knowledge of the specific operating rules and the particular territory involved. The rule focuses on qualification on rules and territory, not on a job title or broader experience.
