What is a requirement for issuing a Rights Over Form L?

Issuing a Rights Over Form L is specifically required to allow an inferior train to pass on single track. This procedure is outlined in operating rules to maintain safe and efficient railroad operations, especially in situations where a train that has lesser priority must be allowed to overtake a train of higher priority.

In single track scenarios, it is vital to manage the flow of train traffic effectively, ensuring that the right of way is granted appropriately without compromising safety. This issuance provides clear communication between the involved train crews and dispatchers, thereby reducing the risk of conflicts or accidents.

The context of single track operations highlights the importance of prioritizing train movements, and the Rights Over Form L is a formal recognition of this need. This practice also ensures that all personnel are aware of the temporary change in the usual operations, allowing for a systematic approach to managing train schedules.
