The Switchboard

The Switchboard is a location in the Commonwealth in Fallout 4 and is the location of the quest Tradecraft.

Background
In pre-war times the bunker was used as a secret base of operation for The Defense Agency as can be seen written on the floor in the main hall. In closer timeline it was used as The Railroad's HQ, its secret location proving to be a protection from the Institute if only for awhile.

Layout
There are two possible ways to enter. One is an elevator hidden behind a bookshelf in the basement of a Slocum Joe, a pre-war donutshop. The other is through the old escape tunnel that exits through a drainpipe.

The base itself is a concrete bunker in two floors. The place is crawling with Synths but some of the defense systems built by The Railroad lies dormant and can be activated by the sole survivor and can be used to take out some synths.

Notable loot

 * Two hazmat suit can be found on a table on the second floor near where the quest item for Tradecraft is located.
 * One Mini nuke on a shelf to the right of Carrington's prototype.
 * Fusion core in the lower level generator room.
 * Fusion core by the elevator behind a locked security gate.

Appearances
The Switchboard appears only in Fallout 4.
