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 the mysterious Railroad faction. If you preferred to go to Diamond City, the characters you need to eavesdrop 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 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

Observe the red brick path on the ground heading away from a stamped seal just in front of the fountain. The subsequent step is to follow this brick path as it will take you to the several traditional tourist locations throughout the city. There are seven more sections after the original starting point, and each of these sections emphasizes a clue for unlocking the door to the Railroad’s secret hideout. The hideout is located at the spot which can be found at the end of the tour.  

Every tour stop is going to have a city seal on the ground with a particular letter and number written on it. Record each of these symbols, as they are clues for preparing to get into the hideout later. There are eight of these embossed seals total, including the one at the first fountain that states “A7”. 

The next tourist locations and seal symbols are as follows: 

• Nearby the perimeter of Boston Common, watch out for a seal near the Massachusetts State House. The seal states “L4”. 
• Proceed onwards to the trail of the Old Granary Burying Ground. Be combat-ready because you’ll have to fight off some Ferals, then take note of the marked seal that states, “A2”. 
• Continue going forward on the brick path via the Old State House. There is a seal that states “O6”, adjacent with some bloody entrails. 
• Proceed on to the Old Corner Bookstore. Man up, as there are numerous types of attackers found here. The seal here is labeled as “3I”. 
• As soon as you enter Faneuil Hall, determine the stamp that reads “5R”. Be notably careful when visiting this location, as there is a Super Mutant Suicider and other mutated opponents that will probably hit you if you’re not concerned. 
• Stay alarmed as you extend towards Paul Revere’s House. Destroy the enemies and discover the marked seal that reads “8D”.

The path stops at the Old North Church, with an ultimate clue seal that states “1R”. Although it’s fun to go on treasure hunts like these, you don’t really need to understand the path to determine the final target. If you understand how to find the Old North Church, just head straight there from the origin point in Boston Common. 

As soon as you enter the Old North Church, open the door shown by the marked seal and lantern on the ground. Be combat-ready to fight off a lot of Ghouls once you’re indoors. From here, you need to initiate your way to the church basement. Go ahead through the hole in the wall, and make a swift right through another doorway under some debris. Proceed down the staircase into the hallway and towards 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.  

Joining the Railroad Faction

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 Head Quarters to open this as a fast travel point on your map.
