Which block type is governed by manual control during an emergency scenario?

• A. Normal Block
• B. Modified Emergency Block
• C. Automatic Block
• D. Central Block

Answer: (B)

In emergencies, you need a setup you can control directly to coordinate safety. The Modified Emergency Block is designed for this situation, allowing an operator to manually set the block’s status and manage train movement under direct supervision. This manual control is essential when automatic signaling may be unreliable or needs override to safely route trains or protect the scene. Other block types rely on automatic detection or centralized control, not on operator-driven manual intervention for emergency scenarios. So the block type governed by manual control during an emergency is the Modified Emergency Block.
