The tram was originally in Fallout 3, the broken steel expansion, not NV. The tram hat was used because of limitations in the engine. I assume the obsidian Devs just copied the existing solution for NV. Also more fun, it wasn’t an NPC, it was you, the player character and the tram wasn’t a hat it was a technically piece of shoulder armour.
