A server I created, Minecraft SCP Server has several features. They include an elevated train. But, in a life without man how long will it last?
1 day: The power fails and the train stops.
10 years: Graffito, a house I made, ignites, and it burns. It catches on to the miniature dump truck made of wool, then to the metal phone, and finally the glue. The glue explodes, causing everything to become highly adhesive.
100 years: The sticky paper decomposes, and the virus breaks out of its container, affecting animals.
250 years: All animals in the server, along with some other servers, are infected. The train falls over, but the track survives.
300 years: The track collapses. Minecraft SCP Server is gone.
