Which track is facing to track 2 railing?

The correct choice indicates that Track 1 is the one facing Track 2 railing. In the context of rail operations, tracks are often numbered in a specific sequence, with Track 1 typically situated adjacent to Track 2. Given that Track 2's railing would be on its outer side, Track 1, being next to it, logically faces that railing.

In a typical train yard or station layout, tracks are laid out in parallel lines, and understanding their orientation is crucial for train movement, safety, and scheduling. The adjacent arrangement means that Track 1, when viewed from Track 2, has its side facing the railing, making it the closest track.
