"Through the Snow", a 2013 film

A dystopian movie about the last survivors of an ice age-like apocalypse who take refuge in a specialized train forever circling the Earth. The rich live well in the first cars of the train, while the lower class exists in unsanitary conditions, in the very last section of the train without sunlight, and is forced to eat black plates of "protein bars".
