What action should be taken if a train is placed on a siding or storage track?

When a train is placed on a siding or storage track, it's essential for safety and stability to apply both air brakes and sufficient handbrakes. The air brakes are used to provide a strong initial stopping force and ensure that the train does not move unintentionally. However, relying solely on air brakes is not sufficient in all cases, especially in situations where the gradient might lead to a potential movement.

Applying handbrakes serves as a secondary measure to securely hold the train in place. Handbrakes are particularly important because they offer additional friction and support, especially if there is any issue with the air braking system or if environmental conditions (like wind or slope) could cause the train to roll. Thus, using both systems together ensures that the train remains safe and stable while parked on the siding or storage track.

While notifying control of the train position is important for situational awareness, it does not replace the necessity to secure the train physically. Similarly, merely leaving the train without taking any action or relying only on air brakes would not fulfill safety protocols and could lead to accidents or unintended movements.
