Restless Weald Door Code Puzzle
Go to the southeast side of the ruin as marked in the picture below.
Here you will see the number 1923 (9 is upside down and looks like 6) written on the wall as shown in the picture below.
Enter the ruin through this wall and immediately turn left. Then jump over the wooden barrels as shown in the picture below.
Behind the barrels, you will find a Datapoint. The Datapoint says that the entry code is the year the station was built. So, the number 1923 that you saw on the ruin wall before is the door code.

Go to the northeast portion of the ruins. Here you will see a railcar. Pull the railcar to the starting point of the tracks. Then use the switch to change to the straight tracks. Now push the railcar forward until you reach a ledge.
Stop the railcar below the ledge as shown below. Then jump on the railcar and climb up the ledge. After that walk on the rope to reach the key module on the other side. Pick up the key module.
Then jump down and shoot the red lock to release the ladder as shown in the picture below. Jump on the ledges as shown below to reach the ladder. Then climb up the ladder to reach the locked door.
Insert the key module on the console next to the locked door. Then enter the door code (1923) to unlock the door.
Once the door is open, use the zipline to go through the hole on the wall on the opposite side as shown in the picture below.
Here you will find a firegleam as shown below. Ignite the firegleam to blow up the wall. You will be able to do this only after you have completed story quest 5, Death’s Door.
Now go back to the railcar and pull it back to the starting point of the tracks. Then use the switch to change to the curved track. Push the railcar and take it inside the ruins through the hole on the wall that you created by igniting the firegleam before.
Stop the railcar below the ledges as shown in the pictures below. Then jump on the ledges to reach the ornament. Pick up the ornament to complete the “Restless Weald” Relic Ruin.
