If foul time is being used and sidings are blocked, who must be notified?

When foul time is in effect and sidings are blocked, notifying the manual interlocking and control point is crucial for several reasons. The control point is responsible for the safe operation and management of train movements in the area. By informing them, you ensure that all operations that may be affected by the foul time are coordinated properly.

Additionally, this notification allows the control point to manage any potential conflicts or hazards that could arise due to the blocked sidings. It helps maintain safety protocols, ensuring that all trains in the vicinity are aware of the situation and can act accordingly to prevent accidents or delays.

The other options do not fulfill the same critical safety and operational requirements as notifying the manual interlocking and control point. For instance, while notifying nearby trains might seem logical, the direct responsibility for managing train movements lies with the control point, making them the essential contact in this scenario.
