The Sub-Train is a self-contained train withing a train. It runs almost the entire length of Snowpiercer and is divided into three categories, one for each of the Classes[1].
Description
The Sub-Train is a monorail track design with a single suspended narrow guideway, which means only one train car run at any given time. It's possible that horizontal switching takes place. The monorail system is separated into three sectors, each of one of the Classes, which means technically up to three carts in various directions can run the length of each sector. Considering the length of the train, the Sub-Train is used regularly by the characters, even though it is shown only a few times.
Under the Sub-Train tunnel also lies a narrow maintenance corridor that provides access to the underside of the train which contains mechanical parts like hydraulics control. In case the Breachmen needs to access these tubes a semi-transparent membrane is erected around the affected parts of the train, as for the heat to not leak out.
The Sub-Train tunnel also has a hydraulic system to keep the train steady. Damage to the system caused the Torreta canyon crisis.
