Humans (Snowpiercer)

The Snowpiercer is a gigantic, perpetually moving train that travels a globe-spanning track, carrying the last remnants of humanity after a failed attempt at climate engineering to stop global warming that has created a new Snowball Earth. The lower-class tail-section passengers continuously rebel against the elite of the front of the train due to harsh living conditions. The mysterious Mr. Wilford is the creator and architect of the train.
