What action should be taken prior to moving past a Block Limit signal?

Prior to moving past a Block Limit signal, it is essential to ensure that the train order is in hand. This is a critical safety measure, as train orders provide the necessary instructions regarding the movement of the train, including any restrictions or allowances that might affect the journey. Train orders are vital to maintaining the safe operation of all train movements, particularly in areas with complex track configurations or when multiple trains may be operating in close proximity.

Having the train order in hand confirms that the crew is fully informed of any specific instructions that may impact their route, including speed restrictions, track permissions, or any other critical information necessary for safe operation. This step ensures that the crew is prepared and compliant with operational protocols, thereby minimizing the risk of incidents as the train approaches or moves past the Block Limit signal.
