Chapter 12 in Wolfenstein: The New Order videogame is named Gibraltar Bridge and it is available after you discover the Daat Yichud secret vault at the end of the previous mission.

The chief research scientist is travelling on the Gibraltar Bridge in a train, so Blazkowicz must steal his identity in order to gain access to the lunar shuttle.
Chapter 12 doesnt feature any commander and considering the disaster at the start of the mission the collectibles may prove hard to find.

Wolfenstein: The New Order Chapter 12 Collectibles Guide
Map
Before you deploy the spindly torque from the helicopter, turn around and grab the bridge Map from the seat.
Enigma Code #1 (Piece 6:6)
Once you jump from the helicopter head inside the first train and kill the soldier. Next to him is the Rocket Launcher upgrade for the Assault Rifle. Go through the second train while killing the rocket launcher soldier and turn right (watch out for the turret).
Go across the beam and the use the LKW to cut / shoot the chain of the suitcase that is cuffed to the dead soldiers hand. When the suitcase drops on the ground it opens and you can collect the Enigma Code thats inside.
Enigma Code #2 (Piece 6:7)
Continue your way on the train car with the turret, but do not jump down inside the next train. Instead, jump on the bridge and turn left.
Head through the door and go up the stairs to find the second Enigma Code in Chapter 12.
Enigma Code #3 (Piece 6:8)
Go back on the train with the turret, but this time you should fall down into the next train. The train is a double decker and it crashed on one of its sides.
Therefore, kill the soldier thats inside and then crouch where he is and go to the left and all the way to the end to grab the Enigma Code piece.
Enigma Code #4 (Piece 6:9)
Exit the train and before heading inside the next one check next to the side entrance to find the fourth Enigma Code near the edge of the bridge.
Enigma Code #5 (Piece 4:1)
Head into the train and use the beam to get across in the next train car.
There is a large hole in the left side of the train car. Right by the hole is a seat and under the seat is the Enigma Code collectible.
Gold #1 (Gold Army Man)
Eliminate all the soldiers that are shooting you and then go around the double decker train. The first Gold piece is on the bridge, next to the huge gap.
Gold #2 (Gold Compass)
Now head inside the train and use the opened hatch on the second floor to get on top of the train. Use the beam behind you to get in the next train car.
Cut the fence with the laser and then jump on the crates to find the Gold piece on a box that cant be reached otherwise.
Gold #3 (Gold Rabbit)
When you get on the other side of the bridge you can see the train car that has four supersoldier pods. From the last one (numbered 4) a supersoldier will come out to attack you.
After you defeat him go inside the pod to get the Gold collectible.
Enigma Code #6 (Piece 4:2)
There are a few ways to get the sixth Enigma Code, but one involved jumping from the last train car before jumping on the bridge and it was a little difficult.
From the previous collectible go up a little bit and you should see a concrete crossbeam on your right that can be used to get higher.
Once up there you can either use the metal beam on the left or jump on the train with the pods. Jump on the train, head across the beam, then use the U-shaped path on the other beams to reach the collectible.
Enigma Code #7 (Piece 4:3)
Continue with your mission and go at the top of the building. Near the turret is a metal cover in the floor. Cut it and get inside.
Kill all the enemies and then stand in front of the shelves that are on the left side of the room. To get the Enigma Code piece break the rightmost box on the shelf.
Enigma Code #8 (Piece 4:4)
After you jump out from the helicopter again, head inside the room on your right. The final Enigma Code collectible in on top of the safe.
