What should a conductor do when there is a blue signal 10 car lengths from the switch on track 2?

When a conductor encounters a blue signal, it indicates that work is being performed on or near the track, and it serves as a warning for the conductor and other train personnel to ensure safety in that area. The blue signal is specifically intended to inform the crew to not enter or operate in that section of the track without proper clearance.

By choosing not to block the view of the blue signal, the conductor ensures that all personnel can see it. This visibility is crucial for maintaining safety protocols, as it allows anyone near the area to be continuously aware that a work crew is present. It also prevents any confusion that might arise from obstructed signals, which could lead to dangerous situations if someone inadvertently operates without recognizing the work zone's status.

In essence, keeping the blue signal visible upholds the safety procedures in place, reinforcing the importance of adhering to signaling and operational protocols on the railway. Thus, this choice demonstrates understanding and compliance with established safety practices.
