Explanation:

1. For the outside train: Using the tunnel as a fixed reference point, the train is positioned approaching the tunnel, and is moving toward the tunnel (its distance from the tunnel decreases over time).
2. For your train: Using the outside train as a reference, if the outside train moves toward the tunnel, your train appears stationary relative to your own seat, and relative to the outside train, your train is moving backward; or if using the tunnel as a reference, your train is stationary while the outside train moves.

Answer:

1. Position and motion of the train outside the window:

The train is positioned in front of and approaching the tunnel. It is moving directly toward the tunnel, getting closer to the tunnel entrance with each moment.

1. Position and motion of the train you are sitting on:

Relative to your seat (or the interior of the train), the train is stationary. Relative to the moving outside train, your train appears to move backward; relative to the fixed tunnel, your train remains in a constant position.
