This area includes the family house, the shop, and the salvage yard transformed by raiders to include platforms and such. In the salvage yard is a train car with a bunker. It appears that previously, a battle was fought between super mutants and raiders, with the former coming out on top and claiming residency.
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. Walk north-northwest a little as the view of the train car will be obscured by the bush and tree in front of you. The train car is on the other side of the rusted chain-link fence; although it's a long rectangle (like many of the other jumbled containers in the yard), the train car is bright blue on three sides, and its exposed underside is brown and tan, with the rusted trail-wheel assembly visible. To enter the train car, go to the back of it and jump and use the disassembled refrigerator doors as a ramp to get on top.
- Railway rifle - in John Miller's bunker. It is located in a blue railway carriage just behind and to the right of his house, beyond the wire fence, as you exit the rear of the house. If you are having trouble finding it, look for a wire that runs through the junkyard and follow it. It also respawns as soon as the location itself resets.

- ps4 pc Turning the generator on before attempting to open the bunker could cause the glitch mentioned above, but before actually entering for the first time. [verified]
