Speak with Father

After completing Powering Up, go back to Father and he will tell you to eliminate one of the Institute's enemies, The Railroad.

Powering Up Walkthrough

Kill Desdemona and the Other Leaders

Fast travel to Old North Church and enter it to go underground where the Railroad HQ is. Eliminate Desdemona who is waiting for you, alongside the other leaders of the Railroad.

You can also side with the Railroad after arriving to the Railroad HQ but this would mean betraying The Institute and as a result, you cannot unlock the rest of the Institute's questline.

Go Back to Father

After dealing with all of the Railroad, go back to the Institute and speak with Father to deliver the great news. The quest will end while speaking with Father.
