The first thing that catches the eye as the J‑Girl pulls into the station is its curve‑lit silhouette, a sleek ribbon of brushed steel and iridescent glass that seems to breathe a soft, humming glow. The name “J‑Girl” is emblazoned across its side in a stylized, neon‑pink font that flickers in rhythm with the train’s own pulse—a living billboard for the city’s restless heart.
