During coupling, why is it essential to monitor the speed closely?

Monitoring the speed closely during coupling is crucial primarily to prevent accidents and maintain safety standards. Coupling involves joining two trains or train units, which requires precision and care to ensure that the connection is made safely. If the speed is too high during this process, it can lead to significant risks, including the possibility of jackknifing, derailments, or injury to crew members and personnel present in the vicinity.

When coupling is executed at inappropriate speeds, the physical forces involved can exceed safe limits, compromising the integrity of the couplers themselves and potentially causing severe damage to both trains. Additionally, maintaining a safe speed helps train operators respond quickly to any unforeseen circumstances or failures that may arise during the coupling process, thereby enhancing overall safety through diligent speed management.

While other factors like equipment wear, operational efficiency, and train dispatching times are important, they are secondary to the paramount importance of ensuring safety during the coupling procedure. Safety protocols dictate that speed must be monitored closely to protect all personnel involved and to maintain the safe operation of the railway system.
