What should be verified before coupling at the point of the add?

Before coupling at the point of the add, verifying coupler alignment is crucial for several reasons. Proper coupler alignment ensures that the two trains connect smoothly and securely, which is essential for the safe operation of the train. Misaligned couplers can lead to mechanical failures, derailments, or unsafe conditions if the coupling is not properly established.

Safety protocols in rail operations emphasize the importance of checking the physical alignment of the coupler components, as misalignment can result in damage to both equipment and infrastructure, as well as injury to personnel. When couplers are correctly aligned, it allows for efficient transfer of power and helps maintain train integrity during operation.

The other factors, such as the speed of the train, track conditions, and air pressure levels, while important for overall safety and operational efficiency, are not directly related to the immediate requirement of ensuring a successful and safe connection at the coupling point.
