Powder Gangers

Powder gangs are packs of criminals from the eastern parts of the New California Republic. When NCR attempted to expand east, they needed railways to carry supplies to distant locations, especially places ripe for colonization. For this task, NCR used criminals from their Black Canyon prison who were approaching the end of their sentences. Unfortunately, when NCR started to have financial problems, payments to the workers started coming up late or short. Eventually, the workers decided to take matters into their own hands, seizing the work stations and all the blasting powder they could find. They became powder gangs, blowing up any and all caravans and railways they came across.

Appearances
The powder gangs appear in Fallout: New Vegas. They were also mentioned in Van Buren design documents.
