What is the coupling speed specified?

The coupling speed specified at about one and a half feet per second is crucial for ensuring safety and efficiency during the coupling process of train operations. This speed is designed to allow for a controlled connection between train cars, reducing the risk of damage to the equipment or injury to personnel involved in the operation. Coupling at too high a speed could lead to rough impacts that may cause mechanical failures or safety hazards, while coupling at too low a speed could prolong the process and create inefficiencies.

Understanding the rationale behind this standard helps train operators maintain best practices in coupling operations. It reflects a careful balance between operational efficiency and the safety of both the rolling stock and crew involved in the maneuver. The specified speed is based on extensive research and operational experience in the field.
