When connecting two railcars, what is the first step?

When connecting two railcars, the first step involves aligning the couplers and using the coupling lever to secure the connection. This process is critical because proper alignment ensures that the couplers engage correctly, which is necessary for a secure and safe connection. The coupling lever helps lock the couplers together, preventing any unintended disengagement during movement.

Taking this step first is essential to facilitate an effective coupling procedure. Other safety measures, such as securing connections with chains, checking air brakes, and ensuring personnel are at a safe distance, are important but should come after the initial connection is made. Ensuring that the couplers are correctly aligned and engaged lays the foundation for a safe and effective operation, particularly when considering the dynamics of railcar movement and the importance of stability during transport.
