The 'cut-in' procedure specifically involves the integration of a new locomotive into train service while the train is already in motion. This is a critical operation that requires careful coordination to ensure that both the new locomotive and the existing train consist operate smoothly together. During a cut-in, the new locomotive must be properly linked in terms of electrical and air brake systems, and the crew must conduct checks to confirm that everything is functioning effectively before the full capabilities of the locomotive are utilized.

This process is often essential for maintaining the efficiency and performance of train operations, especially when additional power is needed to handle gradients or heavy loads, therefore it emphasizes the continuous operation and flexibility required in freight services.

Understanding the cut-in procedure is important for conductors as it highlights the need for attention to safety protocols, proper teamwork among crew members, and knowledge of locomotive systems, all of which contribute to the effective and safe operation of the train.
