After the completion of the mission Burning Cover given from Doctor Carrington if the player talks to Predictive Analytic Machine (PAM) it will say that for the stability of the Railroad is vital to exapand themselves with another settlement. It then proceeds to give the Sole Survivor the task of liberating Taffington boathouse from what's infesting it and to build defenses for the place.
