The audio starts with the soft hum of a train in motion. There is a soothing rhythm to the sound, a continuous lullaby that encapsulates the essence of commuting. The subtle clatter of the rails forms a gentle undercurrent, bringing to life the image of a train gliding seamlessly across its track. The inside of the train is quiet, almost eerily so, a stark contrast to the usual hustle and bustle associated with such a mode of transport. The murmur of the engine is the only indication of movement. There is the soft rustle of fabric every now and then, hinting at the presence of a lone passenger or two, each engrossed in their own world. The occasional squeak of the train against the rails punctuates the silence, serving as a reminder that this is indeed a journey in progress. The audio paints a picture of tranquility amidst movement, a silent voyage within the confines of a train.
