What type of track positioning is indicated by "Track 2 facing to Track 1 trailing"?

The phrase "Track 2 facing to Track 1 trailing" indicates that Track 2 is oriented in a direction where it can connect to Track 1, which is positioned behind it in the direction of travel. This scenario describes a situation in which two tracks run parallel to each other, allowing trains to operate in both directions on the respective tracks.

In a dual track operation, trains can efficiently move back and forth on two separate tracks, which enhances the overall capacity and flexibility of the rail system. This setup is critical for managing train schedules and minimizing delays, as it provides a more robust framework for trains to navigate without forcing them to wait on a single track.

The other options do not apply here; single track movement refers to operations on a single track, limiting flexibility and capacity. A track crossover involves changing tracks at junctions rather than just running parallel. Train passing generally occurs when one train overtakes or goes around another, which may not specifically apply to the alignment described. Thus, the indication of Track 2 facing Track 1 aligns perfectly with the concept of dual track operation.
