The repair yard sits beside a set of railway tracks which the New Appalachian Railroad's trains used to travel on. The small location contains a control tower, parking space and a Quonset hut which acts as a workshop area. The hut contains an armor workbench, two explosives crates, and assorted junk and tools. There is also a locked safe (Picklock 2) in the control tower.
Potential Vault-Tec bobblehead - In the control tower, on a filing cabinet.
The NAR repair yard appears only in Fallout 76.
