If communication fails while issuing track and time, how is it considered?

When communication fails while issuing track and time, it is considered issued and in effect to ensure safety and operational continuity. This principle is based on the understanding that track and time orders are critical for the safe passage of trains over a section of track. If the communication process is interrupted, there must be a mechanism in place that recognizes the order as still valid. This ensures that any trains already operating under the issued track and time can continue their actions based on the assumption that the order remains effective, thereby preventing potential confusion or operational hazards that could arise from the communication failure.

The choice reflects a safety-oriented approach in railroad operations where maintaining adherence to issued orders is vital. It helps prevent any misunderstanding that could lead to accidents, as all personnel involved would regard the issued track and time as active until there is formal communication that indicates otherwise.
