Which of the following is NOT a safeworking system for UGL?

The answer identifies the Automatic Signal System as not being a safeworking system for UGL. To understand why this is correct, it's essential to define what a safeworking system is and how it operates within the context of rail operations.

A safeworking system is a set of procedures and technologies designed to ensure the safe movement of trains and to prevent accidents. Common systems include those that provide commands or information to train operators regarding the movement, positioning, and speed limits of trains, thus maintaining control over rail traffic.

The Automatic Signal System is primarily focused on using mechanical or electronic signals to direct train movement automatically, relying heavily on technology rather than the procedural or manual interventions found in other safeworking systems. While it does play a role in general rail safety, it does not conform to the specific operational frameworks established for UGL, which involves more direct human supervision or specific procedural guidelines.

In contrast, systems like the Train Order System, Manual Block Working, and Alternative Train Order are structured around operational rules and manual methodologies that designate how rail movements are controlled. They ensure compliance with safety protocols through direct intervention, which aligns with UGL’s operational requirements. These systems emphasize communication and coordination between train crews and control centers to maintain safety
