What is the first action you should take upon receiving confirmation to secure your train at McPherson?

The first action to take upon receiving confirmation to secure your train at McPherson is to apply all brakes. This action is crucial because it ensures that the train is fully controlled and will not move unexpectedly while you prepare to secure it. By applying the brakes, you create a safe environment for the next steps in the process of securing the train.

Securing a train involves multiple safety measures, and applying brakes holds the train in position, preventing any potential rolling or movement. This foundational step is essential, particularly in freight operations where various factors—such as grade, wind, or load—might affect the stability of the train.

Once the brakes are applied, other actions like notifying the dispatcher or performing an air test can follow, but ensuring the train is securely held in place by applying the brakes is the priority. This understanding of train handling and air brake operation is vital for maintaining safety in the rail industry.
