Confirming with the dispatcher that the "Track Out of Service" (TOL) indication is displayed is essential because it verifies that the main track has indeed been officially designated as out of service for the duration of the work. This step is critical to prevent any potential conflicts with train movements and to ensure that all personnel involved in the work are safeguarded.
