What does the term 'trailing' indicate in track orientation?

The term 'trailing' in track orientation specifically refers to the direction in which a train is moving. When you hear 'trailing,' it typically describes how a train follows along the tracks and indicates the flow of train traffic. This concept is essential for train operations, as it helps to establish signals, switches, and other operational protocols in relation to the direction of train movement.

Understanding track orientation is crucial for safety and efficiency in train operations, where clear communication about the direction trains are supposed to go can prevent accidents or miscommunication within the transit system. Other considerations like train length, cargo weight, or signal types are significant for different operational aspects but do not capture the essence of what 'trailing' indicates in the context of track orientation.
