This video guide will dive into the Railroad Faction’s “Road to Freedom” Quest with a walkthrough:

Tips: What makes this particular quest tricky is the lack of waypoints and map markers. The quest can be started in several ways: by overhearing people in Diamond City Market or by progressing in the “The Molecular Level” main quest. The first waypoint at Park Street Station will show up on your map.
Now normally the quest wants you to follow some lanterns and pick up password pieces along the way. But you can skip all that. Just head directly to Old North Church. Go to the basement and enter the password “Railroad” and you’re in. To actually join the Railroad you must complete the follow-up quest “Tradecraft” which then unlocks a trophy / achievement with the same name. The quest is given to you by Deacon after your first talk with the Railroad leader.

There you go! All Factions trophies / achievements in Fallout 4 are yours to unlock! 🙂
