What is the first step in the procedure for coupling with a cab at the point of the add?

The first step in coupling with a cab at the point of the add is to stop ten feet away and verify that the couplers are aligned. This step is crucial because proper alignment of the couplers is essential for a successful coupling operation. If the couplers are not aligned, it can cause difficulties or even damage the equipment when attempting to connect. Ensuring that the train stops within a safe range allows the crew to assess the situation visually and make the necessary adjustments.

Performing this step first ensures that the following procedures can be executed smoothly and prevents complications that might arise from misalignment. Once proper alignment is confirmed, the crew can then proceed with charging the train and checking connections, notching up the locomotive, or verifying that angles are opened, all of which are contingent upon having the initial step done correctly.
