Isometric Subway Network Illustration

An isometric cutaway view of a fictional six-line subway network beneath a stylized city, rendered as a clean vector illustration. The ground level shows blocky towers, parks, a river, and tiny taxis the size of grains of rice. Below the surface, transparent earth reveals colored tunnels: cobalt for Line A, tangerine for Line B, mint for Line C, raspberry for Line D, lemon for Line E, and lavender for Line F. Trains glide along each tunnel, each with a small numeric badge. Stations are drawn as glass capsules with platforms, escalators, ticket gates, and miniature commuters. Transfer hubs glow softly where lines intersect. Labels are flat sans-serif: "Harbor Central", "Linden Square", "Old Mint", "Foundry Park", and "Skyline Junction". A legend in the lower-right lists line colors and frequencies. The palette uses muted off-white background, charcoal outlines, and saturated line colors. Light is even and shadowless, with subtle ambient occlusion under buildings. The composition is centered with generous negative space, evoking a confident infographic poster suitable for a transit authority promotional piece.

一座虚构城市地下六线地铁网络的等距剖面图，以干净的矢量插画呈现。地面层是方块状高楼、公园、河流和米粒大小的出租车。地下层透明，可见彩色隧道：A 线钴蓝、B 线橘红、C 线薄荷、D 线树莓、E 线柠檬、F 线薰衣草。列车在隧道中滑行，各自带有数字徽标。车站绘成玻璃胶囊，含站台、扶梯、闸机和微型乘客。换乘枢纽在线路交汇处柔和发光。扁平无衬线字体标注 「Harbor Central」、「Linden Square」、「Old Mint」、「Foundry Park」 和 「Skyline Junction」。右下角图例列出线路颜色与发车频次。配色：米白背景、炭灰描边和饱和的线路色。光线均匀无阴影，建筑下方有微妙环境光遮蔽。构图居中，留白充裕，仿若交通部门宣传海报。
