When trains enter block system territory from suspended limits, they must move at restricted speed until they reach the first signal that is in service. This requirement ensures safety by allowing the crew to have better control over the train's movement and to respond appropriately to any signals or conditions that may arise once they are back in active territory. Restricted speed allows the train to stop within half the distance of the sighting, which is crucial if unexpected obstacles or conditions are present in the track ahead.

This procedure is a fundamental safety measure in railway operations, particularly when transitioning from areas where signals and communication may have been inactive or less reliable into areas where full signal system operations are re-engaged. It ensures that train crews have adequate time to assess the conditions and signals before resuming normal operations.
