What should a Conductor or Engineer do when a clearance card is received?

When a clearance card is received, it is important for the Conductor or Engineer to mark it and hold it for inspection. This action ensures that all relevant information regarding track and equipment conditions is documented appropriately. By marking the clearance card, the Conductor or Engineer confirms that they have acknowledged its receipt and are aware of the stipulated conditions or restrictions. Holding the card for inspection allows the next team member or operator to review the details and ensure that safety protocols are upheld, thereby maintaining operational integrity and safety within the system. This procedure is crucial in managing any potential hazards or requirements associated with the clearance for movement in the rail yard or on the main line.
