The series was continued in two volumes by writer Benjamin Legrand, replacing Jacques Lob, with The Explorers published in 1999 and The Crossing in 2000.

Belleau and the members of her group agree, but Proloff learns that Krimson intends to disconnect the rear cars while his friends are aboard them.

Proloff replaces Forrester as Olga's guardian but realizes that the virus has killed everyone else on board and that his own days are numbered as the train cannot run forever.

Seventeen years later, Puig Vallès joins one of the now semi-regular braking exercises to avoid collision with the Snowpiercer.

Puig decides to follow the radio music to its source, and it is revealed that the train can travel off the tracks by mounting caterpillar treads.

The train finally crosses the frozen ocean and reaches the source of the music, but the explorers are devastated to discover there are no people—only an automated signal.

They turn on beacons allowing the Icebreaker to crash into the station, providing shelter but trapping and critically damaging the train.

The passengers are permitted to join the mice community but are forced to be barcoded and blood-tested, and children and pregnant women are taken away for "special treatment."

It is further revealed that the switchmen have neutered all the mice and performed genetic experiments on fetuses and babies, in a misguided attempt to engineer a perfect human species.

Under disguise as a mouse, Puig uncovers that the nuclear plant that powers the compound is leaking and slowly killing the population.

The story ends in the future: Hunters have just killed a killer whale, and as Puig dies of old age, a glimpse of flowers growing out of a patch of thawed earth is shown.

The third volume, originally slated for release in 2021 and as-yet-unreleased as of 2024, is reportedly set a short time after the extinction event and after Part 2.
