Fallout 4 Guide: How to Join the Railroad Faction

Once Fallout 4 lets you complete the Road to Freedom quest, everyone can opt to become an aristocratic member of the Railroad. In this guide, we’re going to point out all of the details and tips that are going to help you reach this faction’s hidden hideout and discover the Freedom Trail Code.

Serve the Freedom Trail Quest

There are various ways to initiate this quest. One way is to study the Park Street Station area for hints. The second one is to converse with Doctor Amari during The Molecular Level quest, where she suggests seeking out the Railroad faction. Though, the simplest path is to bug in one of the two locations, which is the path we counsel. 

Start this quest by progressing to Diamond City or the Good Neighbor. We chose Diamond City. When you visit, walk nearby and overhear on the locals till you catch some of them discussing this mysterious faction. If you prefer to go to Diamond City, the characters you need to eavesdrop on will likely be in either the Market or the Dugout Inn. 

Simultaneously listening to the commentaries about the Railroad, the quest objective will now turn to “Follow the Freedom Trail”, and a brand-new objective icon will be located on your map. Observe the icon till you arrive near a fountain in Boston Common close to the Park Street Station. In the presence of the fountain, you will discover a board with rough writing that shows, “At Journey’s End Follow Freedom’s Lantern.” There is also a Tour Bot to the right of the fountain, alongside a sign that says, “The Freedom Trail.” The Tour Bot suggests a historical tourist path that curves throughout the city, starting at this location in Boston Common.

Freedom Trail Code

1. Starting Point: Begin at the stamped seal in front of the fountain. Follow the red brick path, which will lead you to various tourist locations in the city.
2. Symbols and Clues: At each tourist location, you’ll find a city seal on the ground with a specific letter and number written on it. Record these symbols as they will be used later to unlock the door to the Railroad’s hideout. There are eight seals in total, including the starting point which states “A7”.
3. Tourist Locations and Seals:
   • Boston Common: Seal “A7”.
   • Massachusetts State House: Seal “L4”.
   • Old Granary Burying Ground: Seal “A2”.
   • Old State House: Seal “O6”.
   • Old Corner Bookstore: Seal “3I”.
   • Faneuil Hall: Seal “5R”.
   • Paul Revere’s House: Seal “8D”.
   • Old North Church: Ultimate clue seal “1R”.
4. Finding the Old North Church: You can follow the Freedom Trail path to reach the Old North Church, or you can head directly there from Boston Common if you know its location.
5. Entering the Old North Church: Once inside the Old North Church, look for the door marked by the seal and lantern on the ground. Prepare for combat as you may encounter Ghouls inside.
6. Navigating to the Basement: Proceed through the hole in the wall and turn right through another doorway. Descend the staircase to the basement corridors.

How to Get the Passcode to the Railroad Hideout

After inputting the password, the wall will thrust to open, exposing a dark chamber with numerous Railroad faction members anticipating inside, one of whom is Desdemona. She will shortly question you on how you came upon finding their hideout. You can decide to be honest, or reserve information. You will ultimately be given provisional admittance, as Desdemona demands your help with a new task.

Subsequently chatting with Desdemona and Deacon, admit the follow-up quest titled Tradecraft. After finishing this quest and responding to Desdemona, you can choose whether or not to allow admittance within the Railroad faction. If you accept, accompany Desdemona to the Railroad headquarters to open this as a fast travel point on your map.
