A part of the long-defunct network of train stations across Appalachia turned by the raiders into a hub of operations.
The train station contains a vendor bot Raider, offering an assortment of weapons, armor, consumables, and other items. It also includes the player character's stash, as well as automated ammunition and medical supply vending machines. This station also has an armor workbench.
Sunnytop station appears only in Fallout 76.
