When coupling equipment, what is the maximum speed?

When coupling equipment, what is the maximum speed?

• A. 2 MPH
• B. 4 MPH
• C. 6 MPH
• D. 8 MPH

Answer: (B)

Coupling operations must be done at a very low speed to keep equipment under control and protect the crew. Moving at four miles per hour is the safest maximum because it minimizes the shock and misalignment risk when the couplers engage, reducing damage to cars, hoses, and brake connections and giving the crew time to monitor and intervene if something isn’t aligned correctly. Going faster increases the chance of a harsh impact, equipment damage, or an injury. Slower speeds, like two miles per hour, are still safe, while higher speeds such as six or eight miles per hour exceed the safe limit for coupling.
