Who issues Form L and who signs it?

Form L, commonly known as "Lineup" or "Line Control" form, is a critical communication tool used in railroad operations to convey information about track conditions, train movements, and other operational requirements. In the context of the LIRR Operating Rule Book, the train dispatcher is responsible for issuing Form L. This position holds authority over train movements within a specified territory and must ensure that all operational directives and safety protocols are adhered to.

The General Superintendent Transportation is involved in the oversight of train operations and can also have a role in ensuring that all documentation, including Form L, is correctly signed and processed. The combination of the train dispatcher issuing the form and the General Superintendent's role in its validation emphasizes the importance of communication and safety in railroad operations. Therefore, this pairing effectively preserves the integrity of train movements and enhances operational safety.

The roles of other individuals mentioned in the other options either do not typically align with the specific responsibilities for issuing and signing Form L or lack the requisite authority to establish the formal communication needed for train operations.
