Big John's Salvage

Big John's salvage is a location in the Commonwealth in Fallout 4. Once the Brotherhood of Steel arrives in the Commonwealth, a battle takes place between them and the resident Super mutants.

Layout
Inside the tipped train car is a hatch leading to a bunker. To open the hatch, follow the wires leading from it to a generator nearby and activate the generator. The bunker is the broadcast location for the Miller Family Radio Signal and the Millers' skeletons (along with the graves of their children) can be found inside. The bunker contains Big John's safe key which can be used to open the Master safe on the second floor of the nearby house and the safe under the register at the front desk of the shop.

To locate the train car, first exit the back door, by the refrigerator, of the only house in the area, then look to the right. The train car is blue.

Notable loot

 * Railway rifle - in Big John's bunker. It is located in a blue railway carriage just behind his house. If you are having trouble finding it, look for a wire that runs through the junkyard and follow it.
 * Tales of a Junktown Jerky Vendor - On the small table with the lantern, inside the caravan perched atop the containers, adjacent to the steamer trunk.
 * Mini nuke - In the same hut as the skill magazine, in an open refrigerator and between the orange storage container and the yellow forklift.
 * Fusion core - Laying behind the shooting range counter.
 * Super mutant arm guards - armor for Strong. In the same hut as the skill magazine.
 * A set of leveled Power armor can be found just east of the house at the South Boston Military Checkpoint.

Quests

 * Cleansing the Commonwealth - This is one of the locations Knight Rhys will ask to cleanse of its inhabitants.

Appearances
Big John's salvage only appears in Fallout 4.

Bugs
The bunker may become sealed again after exit. Reloading the game may have caused this problem. The generator has already been switched on, so there is no way to enter the bunker besides using console.
