Tactical Thinking Walkthrough

Tactical Thinking Objectives

1. Speak to Captain Kells
2. Kill Dr. Carrington
3. Breach the Door to the Railroad HQ
4. Kill All Pinned Railroad Members
5. Reprogram P.A.M
6. Report Back to Captain Kells

Speak to Captain Kells

Head to the command room and walk down the stairs to find Lancer-Captain Kells and Proctor Ingram. Speak to them to learn more about your mission before heading to the Railroad HQ in Old North Church.

Starting Tactical Thinking Will Make the Railroad Hostile

Keep in mind that starting this quest will cancel any active Railroad quests. If you plan to complete those first, avoid talking to Captain Kells. Only return later once you're ready.

Additionally, since Deacon eventually dies as part of the quest objectives, you will also lose him as a companion by the end of this quest.

Kill Dr. Carrington

Go to the Old North Church and clear out all the Railroad agents in the nave, including Dr. Carrington. He will be fighting alongside the Railroad HQ and can be quickly found hiding in one of the cubicles on the left.

Breach the Door to the Railroad HQ

Next, make your way to the catacombs and eliminate all the Railroad agents along the way. When you reach the end, the Freedom Trail will no longer be active. The only way to open the gate is to detonate the bomb attached to it. Activate the bomb to access the Railroad HQ.

Kill All Pinned Railroad Members

Head to the main Railroad HQ and defeat all the remaining members, specifically Deacon, Desdemona, Glory, and Tinker Tom.

Deacon, Desdemona, and Tinker Tom can be taken down quickly, but Glory can be quite a challenge as she is heavily armored and carries a minigun, so she might take longer to defeat. You can focus on her last or use explosives to deal heavy damage to her.

Reprogram P.A.M

Next, head to P.A.M's room on the left and access her terminal to reprogram her. Insert the P.A.M Decryption Program to start the process, then eject the holotape once the decryption is complete.

Report Back to Captain Kells

After eliminating the Railroad and reprogramming P.A.M, head back to Prydwen and report to Captain Kells to end the quest.
