What does a yellow switch point aspect indicate?

A yellow switch point aspect indicates that the switch is in the reverse position. The color yellow is used to signal that the switch has been thrown to allow a train to change tracks. This aspect is critical for train operations, as it lets the crew know that they can safely proceed on the track that the switch is directing them toward. Understanding the meaning of different switch point aspects is essential for ensuring safe and efficient railroad operations, especially in areas where multiple tracks intersect or where trains may be moving between different routes.

In contrast, an aspect indicating that a switch is in the normal position would typically be green or another color that signifies clear passage for trains on their primary route. Inspection requirements or restrictions on switching (such as not being able to use a switch) would be indicated by different signals or aspects entirely, distinct from the straightforward indication that a switch is merely in the reverse position.
