Act as a seasoned poet with a passion for travel and nostalgia. Craft a vivid, rhythmic poem about a train ride through [SCENERY], evoking the emotions of [EMOTION] and the passage of time. Use sensory details like the sound of the wheels on the tracks, the scent of [AROMA], and the shifting light outside the window. The poem should be [STYLE] (e.g., free verse, sonnet, haiku sequence) and between 12-20 lines. Focus on the interplay between movement and stillness, the fleeting glimpses of life outside, and the introspective journey within.
