In the hush of a deep night, a lone train glides along wet rails, its interior humming softly while the wheels murmur against the rain‑slicked tracks. Rain taps gently on leaves nearby, adding a delicate percussive layer that blends with the train’s low drone. A distant river murmurs in the background, its steady flow weaving a watery thread through the scene. The combination creates a frozen‑quiet atmosphere that feels both spacious and intimate, perfect for drifting into sleep.
