5. Get inside the escape tunnel

The Railroad's old base is crawling with older model Synths. Deacon suggests we use the back entrance to get inside and complete this mysterious errand we're on.

Get inside the escape tunnel

5.1. (Optional) Enter base through front entrance

You can't use it becouse the elevator is not powered up so you are forced to use escape tunnel.

6. Get Carrington's Prototype

Somewhere inside the Railroad's old base is a prototype that a Doctor Carrington needs. Deacon says we can expect serious resistance from "Gen 1" and "Gen 2" Synths.

The first terminal inside the sewers is master-locked but Deacon can hack it for you, just talk to him.

Get Carrington's Prototype

Travel through the tunnels and rooms of the Switchboard. 

You will find Power Core Generator in a small room adjacent to the main control room. There is also an issue of U.S. Covert Operations Manual magazine on the desk inside the main control room.

In the end you get to the door that resembles a giant safe. Let Deacon open the door, Carrington's Prototype is on the shelf inside.

7. Leave The Switchboard

Now that we've recovered the prototype from the Switchboard, it's time to return it to Desdemona. She'll be at the meeting place underneath the Old North Church.

Go to the room with elevator, use terminal to power it up, use elevator, move bookcase blocking an exit and go outside.
