I was seven minutes from quitting when the rooftop chimed and the last piece clicked into place. You feel that small shock when a plan finally resolves and the world becomes suddenly smaller. The train line woke, and the valley exhaled.
How to activate the train network in Big Walk
Towers used as fast-travel anchors are a staple of open-world design; the Blue Tower behaves the same way here. I’ll walk you through the actual steps I used, the shortcuts that saved time, and the tiny traps that made me run in circles until I thought of them.
The short version: there are five puzzles scattered around the Blue Tower area. Each puzzle drops a gold-shaped collectible. Place all five on the empty slots on the Blue Tower roof, then use the blue machines beside the tower to shape the key. Finish the five machine stations and the key becomes usable to restore the train network.
How do I activate the train in Big Walk?
Go to the Blue Tower, gather the five gold collectibles, place them on the roof, then run the key through the five blue machines. If you prefer a route, approach from the Red Tower and move left across the map, or use the chairlift from the Green Tower if you solved that one first. I solved Green with friends, then hopped the lift — saved a full ten minutes of climbing.
Where are the five puzzles for the Blue Tower?
The puzzles live in the immediate zones around the tower. Scan nearby ruins, caves, and cliff ledges; each solved puzzle grants one gold shard. If you get stuck, check small elevation changes and shadowy nooks — devs often tuck a puzzle in plain sight. The Blue Tower is a skeleton whose gold teeth you must replace.
Practical tips I use: mark waypoints on Steam overlay if you’re on PC, coordinate with friends on Discord, and if you’re playing on console, use the in-game map markers to remember which node you’ve cleared. If you bought Big Walk on sale it may have been $19.99 (≈€18), so you want that time investment to pay off.
How to use the train network in Big Walk
Train stations in other games often double as social hubs; Big Walk’s stations become places to meet and trade quick info. Once the network is running, walk into any station and open the schedule to see arrival times, then wait on the platform.
The train isn’t the fastest transport in the game, but it does something else: it centralizes players and resources. Use it to move a squad, pass messages, or carry heavy loot without sprinting across hostile zones. I used trains to ferry parts back to base while my team held the perimeter.
If you’re coordinating with friends across platforms — Steam, Xbox, PlayStation — set a meeting station and sync arrival times using the in-game schedule or a short message on Discord. The train also gives you a breathing window to plan your next move; treat it as a mobile command post rather than only a travel tool.
