After doing some more quests for the Railroad, Drummer Boy will inform you that PAM is looking for you the next time you arrive in the HQ. Go to her and you’ll find Desdemona and Carrington talking about the latest development. Join the mission briefing to get this quest. Once done, head to Goodneighbor and find Dr. Amari in The Memory Den.
Talk to Dr. Amari. After talking to her, play the holotape left by H2-22 on the table beside Dr. Amari. Next, head to Malden Center. Upon arriving, you’ll be greeted by Glory. You’ll have the option to work with her or refuse her help. Once ready, head to the Malden Center station.

The red door to the right is chained so continue through the left. After going downstairs, there’s an advanced door to the north, beside the train. There’s a Fat-Man in front of the second train to the SE. The area have several Novice-locked suitcases.
Take the elevator to the NE to reach the lower area. There’s a generator with Fusion Core to the southeast.
Continue following the tunnel and you’ll eventually reach a large area where synths and raiders are fighting. Kill all hostiles, including a named raider Helter Skelter. There’s an issue of Tumblers Today under the duffel bag in the yellow train car to the NE.
The green steamer trunk is located to the southwest with a weapon workbench beside it. Mini-nuke is found among the pile of rubble to the right of the doorway of the exit. There’s also a cooking station in this area.
Go through the other doorway then continue to the next elevator. This will take you behind the chained door. Unchain it and leave the area. Report to Desdemona to complete the quest.
