How will extra trains be governed with respect to opposing extra trains on single track?

Extra trains on single track, especially when they are opposed to one another, are governed by Form L. This is a specific procedure outlined in the operating rules that provides a structured method for managing the movement of these trains. Form L acts as a communication tool between railroad personnel, ensuring that all involved parties are aware of the train movements, schedules, and any necessary precautions that need to be taken.

When extra trains are using the same single track in opposite directions, the Form L helps to organize and coordinate their movements, thus reducing the risk of accidents and ensuring safety. It lays out the specifics such as where the trains will meet, any siding arrangements, and the authority under which the trains can operate.

In contrast, direct communication, standard signals, and radar systems serve different functions and may not specifically address the operational nuances required for managing opposing extra trains. Hence, using Form L is essential for maintaining safe and efficient train operations on single track sections.
