The Railroad HQ is a location in the Commonwealth in 2287.


The Railroad moved their base of operations to the catacombs under the Old North Church after their old headquarters at the Switchboard was raided by the Institute, forcing them to flee the complex through an escape tunnel. Many of their operatives and members died or fled, and the Railroad was almost disbanded.

The entrance to the HQ is hidden and can only be opened by following the "Freedom Trail" and solving the puzzle to unlock the rotating wheel at the hidden door. The crypts may be dark, but they offer protection from attacks and prying eyes and allow the Railroad to keep functioning.


After the Sole Survivor joins the Railroad, they are given free rein in the HQ. There is a large, circular table in the middle of the chamber where Desdemona usually lingers. To the left of the entrance is Doctor Carrington's area with medical supplies and a treatment bed. In the far right is Tinker Tom's corner, containing research equipment, a terminal, and a firing range.

On the other side of the circular table is a rest area where Drummer Boy and Glory can be found (Deacon will also be here if the Sole Survivor chose not to take him as a follower or elected not to send him to a settlement upon dismissal). On the right side is P.A.M.'s chamber, with several large computers and her terminal on the table in the lower section.

There is a chalkboard on the wall showing all of the railsigns. It is revealed that there is another exit from the crypts to the side of the rest area. This exit also serves as an escape tunnel and leads directly to a ruined building with a chained door, located on the surface north of the church.

  • Icon pc.png Icon ps4.png It is possible to become stuck when standing on the white round table in the middle of the main room.[verified]
    • To fix this, crouch and walk away, reload a previous save, or fast travel to a different location.
  • Icon pc.png In the later missions, it's possible for the main door to close without being able to be opened again.[verified]
  • Icon pc.png If power armor is docked in the power armor station it might become corrupted, this will cause pieces of the power armor to go missing and it will be impossible to exit the power armor whilst in the HQ. [verified]
  • Icon xboxone.png There is a bug whereby Railroad missions will suddenly fail, and upon returning to Railroad HQ, they will all turn hostile. This is not a state of formal hostility unless or until the Sole Survivor returns fire.[verified]
