Editing Olga (section)

==History==
Prior to the comics, Olga was used as a luxury train built by Zheng Industries, and was designed to run for 20 days without stopping, where it would run on a custom built track. At some point, Zheng Industries invented a Perpetual Propulsion Engine, which could only work on a small scale at the time, when Mr Zheng predicted a cataclysm however, the company attempted to make the engine work on a larger scale, where due to the help of Alec Forrester, they succeeded on making the engine work on Olga.

During the final days before the freeze, Zheng Industries created an application program, which allowed people to sign up to try get a place on the Snowpiercer, where they would be selected by Mr Zheng based on their skills to humanity. When a person was selected, they would be given a virtual ticket, and a station for them to wait at to be picked up, where it was up to the passenger to make their own way there. Once everyone had been selected, they began driving the train around the world to pick up as many ticketed passengers as they could, however many without tickets would riot at the stations, and attempt to break onto the train.

Between the time-skip from the departure to when the first volume takes place, Forrester locks himself in the engine and Mr. Zheng disappears. 

Many years after departure, a freeloader from the tail named Proloff is captured outside the tail and held quarantined in third class. He is later taken out of third class and walked uptrain alongside Adeline Beau, to talk with the higher-ups of the train to ask them to re-arrange the class system and let the tailies out of the tail. However, Proloff soon finds out that won't be happening, but instead the whole tail will be cut off. At the same time, a virus begins to spread across the entire train, with it presumably being spread by Proloff. He takes this and marches to the engine with Adeline, only to shoot the windows of the penultimate car and kill Adeline. Proloff soon passes out but he is saved by Forrester and taken into the engine. A short while afterwards, the tail section is disconnected, and a while after that, Forrester passes away.

Being left to run the engine for a long while all alone, Proloff starts hearing voices in his head as he tries to look for any signs of life. A while later, he dies and in-habits the engine.

Later, the now run-away train collides with [[Icebreaker]], before being decomissioned and taken into it's cargo bay, where it acts as a generator.  It's unknown what happens to Olga after the events of [[Snowpiercer 3: Terminus|Terminus]].
