By what time must an inferior train clear the time and block of opposing regular trains?

The requirement for an inferior train to clear the time and block of opposing regular trains is specified as 5 minutes. This is crucial for ensuring operational safety and preventing conflicts between trains traveling in opposite directions. By maintaining this time interval, it allows the superior train—typically a regular passenger service or a faster freight service—to proceed without unnecessary delay or risk of collision.

Establishing a clear time buffer of 5 minutes allows train crews adequate time to react to any potential issues and ensures that the tracks are clear, which is vital for maintaining a smooth flow of traffic on the railway. This rule is part of the broader set of operating procedures that govern train movements and interactions on the track, reflecting the importance of timing in train operations to ensure safety and efficiency.
