Which term describes the layout with Track 1 facing train direction while Track 2 is trailing?

The term that accurately describes a layout where Track 1 is facing the direction of the train while Track 2 is trailing is track orientation. Track orientation refers to the specific arrangement and direction of tracks in relation to train movement, indicating which tracks are designated for approach and which for departure.

In rail terminology, having one track facing the train's direction signifies that trains can enter or move along that track, whereas the trailing track indicates a layout where trains would typically move away from it. This concept is fundamental in understanding how trains operate within a station or along a rail line, as it affects the flow of traffic and routing decisions made by train crews and traffic control systems.

The other terms, such as interlocking system, signal control, and train sequence, pertain to operational elements that help manage train movements rather than describing the layout of the tracks themselves. Interlocking systems control which tracks can be used simultaneously to avoid collisions, signal control pertains to controlling train movements via signals, and train sequence relates to the order in which trains are scheduled to arrive or depart. These terms, while relevant to rail operations, do not define the specific arrangement of tracks as track orientation does.
