Where are Dead Section signs installed?

• A. In overhead wires at certain locations specified in AMT-2 Table 5.
• B. On the ground near the DS.
• C. On the pantograph.
• D. Inside the cab.

Answer: (A)

Dead Section signs are placed where they can be seen in the overhead electric system, marking the deenergized portion of the line. They go on the overhead wires at specific locations listed in AMT-2 Table 5 so crews and train operators can clearly see and recognize the dead section. Signs on the ground near the DS wouldn’t be visible to workers who are working up near the catenary, and signs on the pantograph or inside the cab wouldn’t reliably warn anyone about the deenergized section. The overhead placement ensures the warning is in the right place and in the right context for safety and operations.
