You’ll only gain access to this location after completing the Railroad recruitment quests “Road to Freedom” and “Tradecraft”. Also, you can conveniently fast-travel from this location to anywhere in the map.
An issue of Astoundingly Awesome Tales is found on the table beside the Cooking Station.
Has crafting stations and free items for the taking. Carrington can also double as a wasteland doctor, offering normal services. P.A.M is a modified assaultron that has its own room. Later on, it will give you additional quests.
Tinker Tom is the resident merchant of the Railroad. The first time you talked to him, he’ll talk about rather paranoid stuff and you’ll have the option to get a shot of his serum. There seems to be no negative nor positive effects from the serum.
In the HQ’s escape tunnel, there’s a weapons workbench and generator with an active Fusion Core behind a security door. Hack the Expert terminal to gain access.
