Walkthrough[edit]
Head down the freeway "ramp" you took up to Ricky. Turn to the North and start for the marker in that direction. This passage will get you inside the old Railroad HQ. There are vines over the entrance so it does make it a bit harder to notice.
This will lead you into a sewer. Go through the opening in the wall ahead on the right. This leads to a security gate. To the left is a terminal that you can hack (Master). If you cannot hack this terminal, talk with Deacon and have him hack the terminal to open the door.
Go straight down the corridor and then turn to the right and head down. Be careful because to the North is a disabled Machinegun Turret you will need to deal with. It has a Synth guarding it. Deal with the Synth and continue to the North and Northwest.
This leads to a room with a metal walkway. Head out onto a short walkway. You can find loot in the disabled Machine Gun Turrets and the dead body. Grab it then head down the slope just next to the walkway. Be careful because there is another Synth just below.
The tunnel has water on the floor and 5 Synths Defeat them and continue to the Southeast. Another three Synths are waiting just beyond the corner to ambush you.
Follow the passage as it turns to the East. Go down the stairs. Ahead, on the right-hand wall is another terminal. This can be used to reactivate the turret guarding the next entrance.
Continue downward toward the bottom the of the stairs. You will see another pipe in the lower area.
At the end of the pipe, head toward the security gate. Just to the left of it is a Terminal (Novice Hack). Go through the door and head into the next room
On the other side of the door you will encounter a few more Synths that are gunning for you. There are 2 on the ground floor and 3 more on the balcony above.
Talk with Deacon after you clear out the Synths to learn about the facility you are in. Head to the terminal in the office on the balcony level. It is hackable (Expert level). If the Sole Survivor cannot open it, then ask Deacon to hack it for you.
There is a second terminal against the wall in the room that can be hacked as well (Expert level). This one lets you deactivate some traps inside the Switchboard. Open the doors and then head through them.
Inside the doors, head to the left down the first corridor there.
In this first room you will encounter more Synths that you need to kill. Talk with Deacon to learn more about why you are inside the Switchboard and what you are after.
Strategy Guide/Tips[edit]
- You can talk with Ricky Dalton and persuade him Medium for some Sniper support or Difficult for a direct distraction. Both are likely to get him killed, the distraction more so. Getting to the marker location will show a large pipe emerging from the ground. This will be your passage inside.
