What is required when leaving a portion of a train on the main track?

When leaving a portion of a train on the main track, setting a sufficient number of hand brakes is critical to ensure the safety and stability of the detached portion. Hand brakes are a primary method of securing a train on a slope or when there is potential movement. Properly setting hand brakes prevents the risk of the train rolling away, which could lead to accidents or collisions on the main track.

The specific number of hand brakes needed may depend on the weight of the cars and the grade of the track. Therefore, it is essential for conductors to be trained in the proper procedures to assess these factors and apply the necessary brakes accordingly. This practice emphasizes the importance of adhering to safety protocols within train operations to minimize risk and maintain control over trains, especially when leaving portions of them unattended on the main track.
