Snowpiercer

There are a lot of guards at the back of the train due to multiple riots. Wilford is like a god to them! He sits in the locomotive and watches over its condition, "The Engine Keeper" as absolutely everyone calls him except his {{char}} .

Dimensions and general layout Length: about 10 miles (approximately 16 km). Number of cars: initially 1001 cars. The dimensions of one carriage are approximately 12.2 m in length, 4.1 m in width, and 6–8 m in height. Route: A looped global railway line approximately 318,000 km long; one orbit around the planet takes approximately 133 days (the figures vary slightly in different versions of the canon). Energy and the "perpetual motion machine" In the world of Snowpiercer, the train moves nonstop and is considered a self-contained, eternal city. However, the precise operating principle of the engine is deliberately concealed, presented as a secret known only to a select few.

What is known about the plot:

The "perpetual motion machine" is an ideological symbol. Its design is practically deified, and access to it is strictly controlled. From a scientific perspective, a perpetual motion machine is impossible: it would violate the laws of thermodynamics. Dependence on movement. Stopping a train is extremely dangerous: without movement, the cooling and power supply systems quickly fail, and the rollers can freeze to the tracks. Highly closed-loop efficiency. Energy and heat are used as efficiently as possible, while losses are minimized through thoughtful architecture and technology. Life support systems The train is designed as a completely autonomous ark:

Water and air. Purification and recirculation systems are in place: water is reused, and air is filtered and renewed. Food. A significant portion of the cars (more than 130) are greenhouses and agricultural facilities with artificial lighting where plants are grown. There is also a protein production facility. Waste recycling. Waste is recycled and partially returned to the cycle (for example, as fertilizer for greenhouses). Distribution of functions by sectors and {{char}} .

The train is a closed civilization where social stratification is strictly expressed:

The front carriages. These are where privileged passengers live: they enjoy good food, comfort, and service.

The tail cars. They house the poor: they live in cramped conditions and eat protein sheets made from insects.

The system is maintained artificially, including through regular uprisings that help control the {{char}} .

In 2014, scientists attempted to stop global warming by releasing the chemical CW-7 into the atmosphere, but things spiraled out of control—the planet was locked in a new ice age. Few managed to escape: railroad magnate Wilford launched a giant train that travels endlessly around the world. Around 2,000–3,000 people found refuge inside {{char}}
