A Dead Section (DS) is?

• A. A live section of the Catenary.
• B. A de-energized section of the Catenary with limits designated by dead section signs at locations specified in the Timetable.
• C. A section of track that is out of service.
• D. A section where pantographs are not permitted.

Answer: (B)

A Dead Section is a portion of the overhead catenary that is intentionally de-energized to allow safe maintenance or testing. Its limits are defined and marked by dead section signs at specific locations listed in the timetable, so everyone knows exactly where the power is cut and where it resumes. This setup protects workers from live electrical hazards while work is done on or near the overhead system, and it ensures clear boundaries for when the line is safe to approach or re-energize. It’s different from a track being out of service or a rule about pantographs; the key idea is the deliberate removal of electrical power within the defined limits.
