Activating the train in Big Walk is one of the most important tasks to complete, as it makes traveling around the map easy. The job is easier said than done because there are five puzzles to complete. All five puzzles will reward you with collectibles that can be placed on the blue tower to unlock the required key.

How to activate the train network in Big Walk
The train network remains deactivated at first on your save. To activate it, you have to solve the Blue Tower Puzzle. The Blue Tower Puzzle is quite similar to the Red Tower and the Green Tower Puzzles. I solved the Green Tower first with my buddies before approaching the Blue Tower, but that is not necessary.
You can directly approach the Blue Tower from the Red Tower by moving towards the left of the map. If you take my route and solve the Green Tower first, you can use the chairlift from the Green Tower to reach the Blue Tower.
Look for the surrounding areas to solve the puzzles. There are five puzzles to solve, and each one will provide you with a gold-shaped collectible. Bring the collectibles and place them in the empty slots on the roof of the Blue Tower. This will then unlock the key.
Use the blue-colored machines near the tower to shape the key. There are five of them to get your key ready to be used to restore the train network.
How to use the train network in Big Walk
Once the network is restored, head to a station. You can view the schedule to know when the next train is coming. Once it arrives, wait for it to stop at the platform.
The train offers plenty of beneficial tools that you can use to communicate with your buddies. It’s also beneficial for traveling across the map, although it’s not very fast.
