Handling cars over a hump involves specific protocols to ensure safe and efficient operations. The correct approach is to release the cars in cuts of two or less. This method provides greater control over the movement of the cars, minimizing the risk of collisions and allowing for better management of speed and spacing as they roll down the incline.

When cars are released in small cuts, it reduces the likelihood of issues such as excessive momentum that could lead to derailments or damage to the cars or the track. It also allows crew members to effectively monitor the movement and ensure safe operations.

Larger cuts or blocks of cars, on the other hand, pose greater risks due to the increased forces involved, making handling less predictable. By limiting releases to cuts of two or less, safety remains the priority, and operational control is enhanced. This practice aligns with industry standards and safety regulations, emphasizing careful handling of rail cars in hump operations.
