When a train separation occurs, is it necessary to secure the detached portion if standing on a grade less than 1%?

When a train separation occurs, is it necessary to secure the detached portion if standing on a grade less than 1%?

• A. True
• B. False
• C. Not specified
• D. Only if the grade increases

Answer: (B)

The key idea here is how grade affects whether a detached train portion needs to be secured. On a very gentle slope, with a grade under 1%, gravity isn’t strong enough to make the detached portion move significantly on its own. Because the risk of movement is effectively negligible, the safety procedure does not require securing the detached portion in that situation. If the grade were steeper, the potential for movement grows, and securing could become necessary. So on a grade under 1%, securing the detached portion isn’t required, which is why the statement isn’t correct in this scenario.
