Snowpiercer 1: The Escape, by Jacques Lob, illustrated by Jean-Marc Rochette
This is the graphic novel that inspired the movie and TV show. All three have different plots, but the same premise: a worldwide catastrophe had plunged the planet into arctic conditions, and the survivors - possibly the last humans on earth - have stayed alive aboard a luxury train.
The allegory isn't subtle: the front cars are occupied by the privileged few, the middle cars belong to working people, and the tail cars are are crowded with people living in starvation and filth, forbidden to enter the rest of the train.
Proloff, a "tail rat" from the squalid tail cars, breaks into a middle car and is captured. Adeline, an idealistic middle-car dweller, tries to advocate for him. She's part of a movement that wants to integrate the cars, but Proloff isn't concerned with revolutions - he can't focus on anything except getting himself out. Adeline wants to change his mind about that.
The story is as grim as you'd expect, but perfectly drawn, and affecting.
