The Derailment consists of a small train wreck near the center of the Mystery Lake region. Two wolves may be encountered nearby, and a deer carcass can be found at the train wreck. Inside of the train car, there is a chance of finding a corpse, a metal container, a backpack, and, in rare instances, a .303 hunting rifle.
To enter the car with the open door, you must walk up the fallen tree. You cannot enter the train car that is on its side.
