The Sub-Train is a self-contained train within 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.

Trivia
- As showing in the Behind the Scenes video, they only have a small part of the Sub-Train constructed while everything else is added using CGI in post-production.
- The Tunnelmen, including Jakes Carter and Truck, are responsible for maintaining the Sub-Train.
- Each Sub-Train cart has four seats.
- The Sub-Train is accessible, in the battery section of Utility Cars, by a hatch in the floor.
- The Sub-Train is not accessible for the Tail Section.
- As Snowpiercer's crew can close the boundaries between classes ("borders"). The Sub-Train can be blocked as well.
- When Wilford's sabotage of The Engine went wrong, the Tunnelmen were forced to manually disengage the bogie motors, so Big Alice could push with less resistance, in order to jump-start them.
