Find the pressure plate on the central balcony, on the bridge, and stop on it. Note the combination displayed on the ground, which means the order in which you need the green buttons located on the sides - The South-Western (1), North-Western (2), North-Eastern (3) and the South-Eastern (4). Since some of the buttons are behind obstacles, you need to use the remote controlled batarangs instead of the regular ones. You also should not walk off the pressure plate in the meantime.
After you solve the puzzle, look up and use the claw to grab the Datapack.
Start in an elevated place located discernibly to the North of the collectible. Glide Southwards, towards the derelict side-corridor shown in the screenshot.
After you land in a new location, continue to the South. Along your way, you need to use the
explosive gel to make way for yourself. Now, collect the quite well-hidden Datapack.
Datapack 6 (The bridge's inside)
The collectible is in the Boiler Room Maintenance Corridor] between the lower part of the freight elevator shaft and the boiler room.

Determine the correct password (GALVANIZED), which unlocks access to the Datapack.
Datapack 7 (The bridge's inside)
The collectible is in the Train Station]. Locate the venting shafts worked into the floor, jump into any of them, switch to the first-person view. Explore all of the branches carefully, thanks to which you will locate the Datapack.
Datapack 8 (The bridge's inside)
The collectible is in the Train Depot] located to the North of the main area of the Train Station]. After you get there, start by interacting with the generator located on the right, by charging it with the Shock Gloves.
Turn Northwards now and QUICKLY throw the remote controlled batarang. In the first place, direct the batarangs towards the hole on the right of the railway car and then, towards the discharges under the ceiling. Turn the batarangs by 180 degrees now and aim it at the fuse box located on the Eastern wall (the screenshot).
This is not it, yet. Use the hook to climb onto the car and go North. Locate the weakened fragment of the wall and spread the explosive gel. Detonate the charge and collect the Datapack.
Datapack 9 (The bridge's inside)
The Datapack is inside the railway car in the middle of the Train Station]. The collectible can be collected without using the gadgets.
