Transarctica

Everything About Fiction You Never Wanted to Know.
A Cool Train roaming the glacial wastes of Post Apocalyptic Earth during a new ice age...

...And the sun continued to shine its benevolent rays across the top of the opaque cloud layer, hidden from human eyes. The sun continued to shine.

Transarctica is a 1993 strategy adventure game developed by the French software company Silmarils. It was released for the Amiga, Atari ST, DOS, and Macintosh. This game has a poor English translation, but that doesn't stop the game from being enjoyable.

In the year 2022, the world was plagued by Hollywood Global Warming. In order to cool down the Earth, Professor John Merrick decides that nuclear weapons are the solution. By detonating nukes at each pole, a huge cloud of dust and steam would form thick clouds that will block out the sun and cool the Earth. And that's exactly what happened, except the clouds were bigger than they calculated and the Earth cooled down so much it brought about a new Ice Age. With the world in a deep freeze, civilization came to an end, nice job breaking it Merrick. By the year 2714, the world is still frozen, humanity is barely hanging in there, and the sun becomes a thing of myth. Oh, and woolly mammoths are no longer extinct. The only way to travel safely across the frozen wastes is by train, and only the Viking Union controls the worldwide railroad. A cult of sun believers, known as the Ambivalents, are convinced that there is a heavenly ball of light beyond the clouds, and will do anything to prove it. The leader of the fanatical sun cult, you, has managed to take over a Cool Train, the titular Transarctica, and now nothing can stop the Ambivalents from realizing their dream. Except for the other cool trains still owned by the evil corporation.

Tropes used in Transarctica include:

"It was a splendid explosion. Debris spread over hundreds of meters. How could you be so incompetent as to let the pressure build up so high?"
