What is indicated by the phrase "WORK BETWEEN" in the context of track warrants?

The phrase "WORK BETWEEN" in the context of track warrants is significant because it allows a train to move in either direction between specified points. This indicates that the train is granted the authority to operate within the defined segment of the track without restrictions on the direction of movement. In practical terms, this flexibility is crucial for conducting operations or other necessary activities between two given locations, enabling efficient management of train movements and ensuring safety while allowing for operational needs.

Understanding the "WORK BETWEEN" designation helps train crews to navigate and coordinate their actions effectively, particularly in situations where multiple trains may operate in the same corridor or when maintenance activities are scheduled. It clarifies the operational boundaries and permissions associated with the train's movements, ensuring compliance with safety regulations and coordination with other rail activities.
