What does the letter "¡" in the timetable's 4.3 column indicate?

The letter "¡" in the timetable's 4.3 column signifies a junction with another railroad. This notation is critical for train dispatchers and operators as it helps them identify key points on the railway where trains may change tracks or routes. Junctions are essential for coordinating the movement of trains between different rail lines, ensuring that schedules and operations run smoothly.
