The Charleston trainyard is located southeast of the Poseidon Energy Plant WV-06 and is located on the edge of Charleston. There is a wooden control tower next to the railway tracks west of the yard's main building. The trainyard is full of rusted out New Appalachian Railroad rail cars.
The main building contains a large loading bay and a few smaller employee areas that are located along an upper catwalk which runs around the edge of the building. There is a lunch room and several lockers found here. The catwalk also allows access to the "roof" of the building which doubles as a parking lot and connects to the main road. The main trainyard offices can be found on this level. One of the offices contains a locked floor safe (Picklock 1) and a locked terminal (Hacker 1) which controls the safe. The other office contains two desks with a letter of resignation on one of them. There is also a Stealth Boy in this office.
