Train Station
CommunityCommunity-sourced: based on player reports and not yet verified by this site.
The Train Station in Big Walk is unlocked by completing the Blue Tower. Its monorail offers fast travel across the island and is tied to the Big Ride achievement.
The Train Station is the transit hub that opens once the Blue Tower is complete and its key is shaped. Riding the monorail from the station is what triggers the Big Ride achievement, and it is the fastest way to cross the island in the later game. The station area also plays a role in the Red Tower region, where one of the five tower puzzles is named after the train station cannon. Exact station locations and routes are still being documented by this site.
