What is the proper speed for bringing cars together when coupling?

The proper speed for bringing cars together when coupling is 2 feet per second. This slow speed is crucial to ensure safety and mechanical integrity as the cars come into contact with each other. Coupling at a lower speed minimizes the risk of damage to the couplers and the overall structure of the railcars, which can occur if they meet with excessive force. It also allows for better control and a smoother engagement between the cars, reducing the likelihood of derailments or misalignments.

At higher speeds, the impact force increases significantly, which can lead to dangerous situations, including injuries to personnel and damage to equipment. Hence, adhering to the recommended speed of 2 feet per second is essential for maintaining safety standards in train operations.
