Detailed walkthrough

 * 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. You'll find 2A, 4L, 7A, 6O, 3I, 5R, 8D, 1R
 * 4) Inside the Old North Church, in the basement, there's another Freedom Trail marker with a ring that spins, turn it and press the button to spell the word RAILROAD.
 * 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.
