Slocum's Joe (Lexington)

Slocum's Joe is a location in the Commonwealth in Fallout 4.

Background
Slocum's Joe housed a secret pre-War facility called the Switchboard with two entrances: one from the basement and another from a sewer pipe covered in vegetation outside the city. It was used as a secret base of operation for the Defense Intelligence Agency. Post-War, the Railroad used it as their main headquarters until it was raided by the Institute.

Layout
The building contains three floors, including a top floor with kitchen, the first floor with another kitchen and a serving area for coffee, and the basement which is a separate area from the rest of the store. A bookshelf in the basement, under the only working light in the room, contains an elevator to the Switchboard. It cannot be activated until Tradecraft is started.

The basement can be accessed through a locked door southeast of a tipped orange railway car south of Drumlin Diner, inside a sewer pipe entrance that is hidden behind vines. Inside there are multiple terminals and doors that can be picked. There are radscorpions, a turret, and several synths. There are two fusion cores, hazmat suits, and other apparel. In the basement, one can find a U.S. Covert Ops magazine, "Whistling In The Dark," located in an office on a desk that has a computer with a globe. There is also a large door locked behind an inaccessible terminal.

While doing Tradecraft for the Railroad, one may find Gen 1 and Gen 2 synths and two machine gun turrets. Fragmentation mines can be found outside regardless of whether the quest has been started or not.

Notable loot

 * There is a fusion core in the room to the left when entering the basement from the pipe or to the right when coming down the stairs. This is the room with the large Defense Intelligence Agency seal on the floor.
 * There is a U.S. Covert Operations Manual on a desk next to an Expert terminal in the upper level of the basement room.
 * There are two Stealth Boys and a mini nuke inside the vault.
