Road to Freedom

Road to Freedom is a quest in Fallout 4.

Quick walkthrough

 * 1) Follow the Freedom Trail.
 * 2) Continue following the Freedom Trail.
 * 3) Search for The Railroad.
 * 4) Talk with Desdemona.

Detailed walkthrough

 * 1) Acquire the quest in Diamond City or Goodneighbor.
 * 2) Travel to Boston Common and speak to the Tour Bot
 * 3) Follow the red trail on the ground from location to location, looking at the markers as you go along until you reach the Old North Church. The red line on the ground is largely unbroken but there are a few stretches that are obscured by debris.  You'll find the first seal (7A) at Boston Common right near the Tour Bot. The second seal (4L) is in front of the Massachusetts State House. The third seal (2A) is at the entrance to the Old Granary burying ground. The fourth seal (6O) is near the entrance to Goodneighbor. The fifth seal (3I) is in front of the Old Corner bookstore. The sixth seal (5R) is at Faneuil Hall. The seventh seal (8D) can be found in front of the Paul Revere house. The final seal (1R) at the end of the trail can be found at the Old North Church.
 * 4) Inside the Old North Church, in the basement, there's another Freedom Trail marker with a ring that spins. Spell the word RAILROAD one letter at a time by spinning the ring clockwise or counterclockwise and pressing the central button to select each one. The correct letters are R, A, I, L from the word TRAIL, then R, O from the word FREEDOM, then A from TRAIL and D from FREEDOM. If you make a mistake you must start spelling again from the beginning.
 * 5) Once the door opens, go inside and speak to the people there, you can pass a difficult speech check to be told who they are first, or just tell them who you are.  When asked how you found out about them you can pass a speech check to lie, but there's no immediate obvious results of that.
 * 6) At this point you're introduced to Deacon, a spy who has heard of you, he vouches for you and you then get to discuss why you are there.
 * 7) You are then asked if you would risk your life for a synth, either way the quest will complete and you will be offered work by Deacon, but if you say no then Desdemona, the leader of the Railroad, disapproves.
 * 8) Once Road to Freedom is complete Tradecraft starts immediately.

Bugs

 * In some cases, the game will freeze when attempting to enter certain buildings in Boston Commons, including Old North Church, making the quest Road to Freedom impossible to complete. The console command coc OldNorthChurch01 will teleport the player into Old North Church, past the entrance to The Railroad. The console command tcl must be used to go through and open the door to The Railroad properly. Exiting through the front entrance worked afterwards.
