Agricultural Section

Agriculture workers are vital crew members as they are responsible for producing food and maintaining an extremely fragile closed ecosystem.
==Assignments==
Agriculture is one of the most essential parts of the train, both in size and importance, as its cultures and systems produce a variety of food and materials necessary for the survival of Snowpiercer crew and passengers, and might also serve to scrub carbon dioxide from the atmosphere and produce oxygen. Melanie Caville said to Layton that there are 131 cars "just like this one" while standing in a Greenhouse Car, but it is unknown if she was referring to the whole AG-SEC or only the Greenhouse Cars. It is also unclear if Food Processing is part of it.
When discussing the plan to separate 7 cars containing the Jackboot army, the Folgers and their supporters, Melanie Cavill told Sam Roche, Bess Till and Andre Layton, if they can’t reconnect “Then the back half of the train will freeze. And the front half will starve”. When the plan was enacted, Robert Folger said “That’s Agriculture and Poultry. We can’t live without that.” When Big Alice separated for New Eden, the train was divided in Ag-Sec. Also, one of the Pirate Train cars, made from First Class, had a Meat Locker.
Greenhouse Cars are large one-decker cars whose roof is a dome made out of reinforced glass and where crops are farmed on regular cycles using hydroponics, natural and artificial lights:
* Berries (14 cycles/year), including Chili peppers, Grapes, Cherries and Strawberries
* Potatoes (7 cycles/year)
* Cocoa (6 cycles/year)
* Wheat (4 cycles/year)
* Rice (3 cycles/year)
* Sugarcane (2 cycles/year)
* Cotton (2 cycles/year)
* Lettuce, Carrots, Cucumbers and probably other vegetables
* Floridian oranges, Apples, Mangos, Avocados, Bananas, Grapefruits, Olives and probably other fruits
Spice Greenhouse Cars are similar as the Greenhouse Cars but grow spices instead.
Cattle Cars (Pig Cars, Goat Cars, Poultry Cars, Sheep Cars) are one-decker cars with large windows on one side where animals are bred for their meat, milk, eggs, skin, feathers, methane, and manure... Snowpiercer livestock includes pigs, goat, poultry and sheep. It used to include cows too but an avalanche in the Cascade mountains led to the Cattle Car to be breached and its entire livestock to instantly freeze to death and go extinct seven years after departure.
Aquaculture Cars produces a variety of food and products such as fish and seafood. The water enriched by fish wastes also produces a natural fertilizer used within the hydroponics system. The First Class Aquarium and Sushi Bar Car might have been a high-end version of Aquaculture Cars and was directly under the supervision of Agriculture Officer Dr. Jinju Seong.
This section also includes its own Water Reservoir as stated by Jinju Seong when discussing with Bennett Knox and Melanie Cavill about the consequences of the bovine extinction event. An old Apiary Car was closed down after the bee colony collapsed, three years before the revolution, resulting in bees going extinct. Refrigeration Cars are where the crops and food are conserved after farming and before being processed and dispatched.
AG-SEC systems are intricately intertwined and create an artificial yet fragile ecosystem within the train. After the extinction of bovine cultures, Chief Engineer Melanie Cavill had to think of another way to produce necessary methane the cows used to produce (goat farts). When Agriculture Officer Jinju Seong was tasked with devising a way for equal calories between classes, she angrily noted that lootings of AG-SEC Greenhouse Cars, Refrigeration Cars, and Aquaculture Cars at the end of the civil war led to crops destruction and food shortage.

==Trivia==
* Big Alice might also have a Ag-Sec.
*According to Bennett Knox, there are bovine cultures on Big Alice, which means cows could be brought back from extinction if humanity survives at New Eden.
*More power was diverted to Ag-Sec then other cars during the Pirate Train’s absence in order to keep the plants and animals alive.
