Red Line, Car 20

Abandoned Moscow Metro subway car, beige plastic seats with brown ripped cushions tagged in Cyrillic graffiti, scorch-marked plastic walls, dingy pocked floor.

Red Line, Car 20 debuts in book 3 as a battered remnant of the Moscow Metro, its beige seats and Cyrillic-tagged cushions evoking a gritty, post-apocalyptic transit hub within the dungeon's themed floors. The car's scorch-marked walls and pocked floor immediately signal recent violence, positioning it as both a tactical waypoint and atmospheric set piece for the crawlers. Though limited details exist beyond its introduction, the vehicle's distinctive decay foreshadows its recurring utility in later books as a nexus for ambushes, alliances, and escalating chaos.
