Park Street Station

This is part of the main quest “Unlikely Valentine” in which the station will have Triggermen gang members guarding the area. The end of the station leads to the newly constructed Vault 114.

The booth to the left has a Novice Door with materials on the shelves and an Expert floor safe. There’s an Overdue book on the bench before the turnstiles, and a Nuka-Cola Quantum on the vending machine before the stairs.

The Novice door to the SW has a tripwire connected to a Hardened Sniper Rifle. There’s also an Expert safe there. Another Nuka-Cola Quantum bottle can be seen immediately in the end of the NE tunnel.

In the end of the tunnel, you’ll find the entrance to Vault 114. In the entrance, kill the two Triggermen guards. The room the SE has some medical supplies and a Vault-Tec terminal. Go downstairs and follow the quest marker, fighting off more Triggermen along the way. Once you’ve reached the next part of the vault in the large cavern, enter it and drop down below. Continue to the corridor and you’ll find the sliding door leading to the actual Vault 114.
