After a double Pantograph order has been removed when will the Engineer resume normal Pantograph configuration?

After a double Pantograph order has been removed when will the Engineer resume normal Pantograph configuration?

• A. Immediately after removal.
• B. After one mile.
• C. After a predetermined time.
• D. At the next Station Stop.

Answer: (D)

Changing pantograph configuration is a safety-critical action that must be done in a controlled, verifiable way. When a double Pantograph order is in effect, two pantographs are used to meet the operating requirement. Once that order is removed, you don’t revert while moving; you resume the normal configuration at the next Station Stop so you can visually verify the setup, check for any faults, and coordinate with the control authorities if needed. Stopping at a station provides the necessary safety check and ensures proper interaction with the overhead system. Immediate reversion or reversion after a set distance or time would bypass the required verification and could risk damage or improper contact with the catenary.
