Traincar

Traincar is accessible from Underground Apartments.

Contents
At first you spawn in a forest, behind you is an old building blocked. Going to the front, you will see a train station and a weird structure. Clicking on it goes to the Traincar itself.

In the traincar, there is a single dummy and two doors with different color windows. The green one goes back to the forest and the black one goes to Isolated Conurbation.
