复古苏式地铁线路图

一张扁平示意图风格的交通线路图，灵感来自二十世纪中期东欧地铁图，描绘虚构城市 「Krestov」。八条彩色线路以严格的 45 度和 90 度角穿过奶白纸背景：1 号线朱红、2 号线赭石、3 号线森绿、4 号线钴蓝、5 号线梅红、6 号线青蓝、7 号线芥末、8 号线石板。车站为粗实心圆，配粗板衬线西里尔感拉丁字母站名：「Oktyabrskaya」、「Krasny Most」、「Volkov Park」、「Sadovaya Ploshchad」、「Severny Vokzal」。换乘站绘为同心圆环连接两条以上线路。淡蓝河流弧形穿越，黑色桥标横跨。图顶粗体标题栏写着 「复古苏式地铁线路图」，叠层板字。红星标记中央终点站。右下小图例以斜纹色带列出票价区。色调温润陈旧：烟草奶纸、轻微印刷错位、标题块柔和半色调、全幅细黑边框。

A flat schematic transit map in the spirit of mid-century east-European metro diagrams, rendered for a fictional city called "Krestov". Eight color-coded lines run in strict 45 and 90 degree angles across a cream paper background: scarlet Line 1, ochre Line 2, forest Line 3, cobalt Line 4, plum Line 5, teal Line 6, mustard Line 7, and slate Line 8. Stations are bold filled circles with bold slab-serif Cyrillic-flavored Latin labels such as "Oktyabrskaya", "Krasny Most", "Volkov Park", "Sadovaya Ploshchad", and "Severny Vokzal". Transfer stations are drawn as concentric rings linking two or more lines. A river arcs through the diagram in pale blue, crossed by black bridge marks. The top of the chart carries a chunky title bar reading "KRESTOV METROPOLITEN — SKHEMA 1974" in stacked slab letters. A red star marks the central terminus. A small key in the lower-right lists fare zones with hatched bands. The palette is warmly aged: tobacco cream paper, slightly off-register printing, soft halftone shading on the title block, and a thin black border framing the whole composition.
