What aspect would indicate a movement through a diverging route?

The indication of a movement through a diverging route is correctly represented by "Diverging Clear." This aspect means that a train is allowed to proceed through a switch or turnout diverging from the main track at a speed that is safe for the diverging route. The signal aspect conveys that the route ahead is set for divergence and indicates that both the track and the switch are in proper alignment.

In contrast, the other choice regarding "Approach Restricting" does not specifically signal a diverging move; rather, it indicates that the train must prepare to enter a situation where the track could be obstructed, requiring a reduction in speed. "Diverging Approach," while it sounds relevant, typically means the train is approaching a diverging route and needs to be prepared to slow down but does not confirm that the route is clear. The "Stop" aspect indicates that the train must halt, which is not relevant to the movement through a diverging route, as it suggests no movement would take place at all.

Thus, "Diverging Clear" is the accurate term indicating that the route is safe for a train to proceed through a diverging switch.
