To pass a stop block signal and perform station work, what card is required?

To pass a stop block signal and perform station work, the required documentation is a Clearance Card Form K. This form is crucial as it provides the necessary authorization to move beyond a stop signal, ensuring that the train operations remain safe and coordinated with track authorities. The use of this card reflects the importance of adhering to established safety protocols and communication practices designed to protect both train crews and the integrity of the rail system during station work.

Other forms mentioned have different purposes or are related to other types of operations. Clearance Card Form L, for example, pertains to specific work conditions and procedures, while Clearance Card Form B governs other operational functionalities that do not specifically apply to passing a stop block signal for station work. Therefore, the specificity of Clearance Card Form K in this scenario aligns with the operational safety standards for such activities.
