The Train unlocks at the end of this chain. Finishing Blue Tower on its own stops you one step earlier, at the key.
Your Train ticks are kept on this device, so the walkthrough and the 100% checklist see the same progress.
Train Status Checker
Four questions. The first one that is not done yet is the only thing worth doing next.
Have you returned five rewards at Blue Tower?Not yet
Did you take the Blue Key through all five cutters?0 / 5 cutters
Tap a line you have already done. Progress is kept on this device.
The unlock steps and the stop names here were checked against the game in Sep 2026.
NEXT ACTION
Finish the Blue Tower reward step.
The Blue Key is still held at its lookout, so nothing is on its way to the Train yet. Five challenge rewards bring it back to the tower.
Your next action
Return the five rewards at Blue Tower, then release the key.
Why Isn't My Train Moving?
Four things stop this Train, and only the first three are something you can fix on the Blue route.
Fewer than five Blue Tower rewards
Likely answer
The key has not been released, so the route has not started.
Your next action
Return the missing challenge rewards at Blue Tower.
The Blue Key is not finished
Likely answer
Some of the five cutters are still ahead of the key.
Your next action
Finish the next cutter, then check the Train again.
The finished key is not at the Train
Likely answer
All five cutters are done, but the key never reached the Train.
Your next action
Carry the finished Blue Key to the Train and place it.
Blue is done and the Train has not started
Likely answer
This is no longer progression. The railway has not switched to its running state.
Your next action
Treat it as a Train-side problem and check the railway state.
Progression problem or railway problem?
Blame the Blue route
A missing reward, an unfinished key or a key you are still carrying. Fix it on the Blue Tower route, then come back to the Train.
Blame the railway
The finished key is at the Train, so the Blue route is not your problem any more. Sort the Train out instead of redoing Blue Tower.
You placed the key and nothing happened
Placing the key is the last Blue step, so your side of the chain is finished. If the railway is still silent, it is the Train that has not started, not the key that failed.
Your next action
Check the railway state, then try the Train again.
What's Wrong With Your Train?
Pick the line that sounds like you, and the answer follows from your own state instead of a general checklist.
Your situation
I haven't seen any Train move
Likely answer
Then the route has not started.
A Train no one has seen moving is almost always an untouched Blue Tower. Start with the rewards and the route follows.
Your next action
Open the Blue Tower route and start at the rewards.
How to Unlock the Train
The unlock runs from the Blue Tower rewards to a moving railway. In order:
- 1
Return five challenge rewards at Blue Tower.
- 2
Release the Blue Key at its lookout.
- 3
Take the key through all five cutters.
Blue Cutter 1Blue Cutter 2Blue Cutter 3Blue Cutter 4Blue Cutter 5
- 4
Carry the finished key to the Train and place it.
- 5
The railway starts running and the Train can be boarded.
Blue Tube Lookout → BigKeyComplete → Train
The Blue Key is the one that ends at the Train. The other four keys end somewhere else, so a finished Red, Green or Yellow key does not move this railway.
Where Is the Train?
The railway itself, the place where the key goes and the stops are three different things.
Where the key goes
The finished Blue Key goes in at the Train itself, at the end of the Blue route. That is the last Blue step, and it is the one the checker watches.
The stops
Six stop names are mapped so far. Each one is its own place on the island rather than a menu entry.
How to Use the Train
Boarding, riding and stopping are three different things, and only the first one needs you to be in the right place.
Getting on
Stand at one of the mapped stops and wait. The Train comes to you, so there is no destination to choose and no button to press first.
Riding
Once you are on, the Train carries you along the railway. Time on board is what Big Ride watches, so a proper ride is enough.
Slowing and stopping
A lever on board slows the Train or holds it in place while you step off. It is a ride control, not part of unlocking the railway.
Player-tested routes describe a continuous loop rather than a fast-travel menu, so treat the Train as a moving part of the world you step onto.
What Is the Train Useful For?
The railway changes how you cross the island, not what you have unlocked.
- Crossing the island without the walk
- Regrouping with other players who are somewhere else
- Getting back to an earlier region quickly
- Reaching challenges that sit beside a stop
- Being on board long enough for Big Ride
Does the Train Stop at Stations?
Yes, but not by itself.
Player-tested routes describe a Train that keeps working its way around the loop instead of pulling in and waiting at every stop. If it rolls past you, that is the normal behaviour rather than a fault.
The onboard lever is how you bring it to a stop. Nothing on the platform does that for you.
Known Train Stations
Six stop names are mapped so far. Each one is a real place you can wait at.
What's been mapped so far
- Green Diffuser기차 정류장
- Ring Room기차 정류장
- South Valley Beach기차 정류장
- Sports Valley기차 정류장
- Trap Room기차 정류장
- Upper Hub기차 정류장
The stops are not numbered here, because no running order is confirmed. Use this list to recognise a stop you have found, not to plan a route between them.
Two of these names also belong to challenges elsewhere on the island. The Train stop and the puzzle are different things, and a search for the station gives you the stop.

The Train is mapped as one landmark, so the map opens on the railway rather than on individual platform pins.
기차는 어디로 가나요?
철도는 섬을 한 바퀴 도는 순환선이에요.
지금까지 정류장 이름 여섯 개를 확인했지만, 정류장 순서와 한 바퀴를 도는 데 걸리는 시간, 어느 방향으로 도는지는 아직 밝혀지지 않았어요. 순서가 확정될 때까지는 노선 순서를 그리지 않아요.
아직 확인되지 않았어요. 제보를 환영해요.
Big Ride Achievement
Big Ride is a riding achievement. Unlocking the Train is not the same as earning it.
What Should I Do After Unlocking the Train?
The Train does not hand you a next area. It opens movement, so the route that matters next is whichever one your own save still has open.
What Should I Do Next?That tool reads your saved progression and names one objective instead of sending everyone to the same place.
Big Walk Train FAQ
Big Walk에서 기차는 어떻게 해금하나요?
파란 탑에서 도전 과제 보상 다섯 개를 반환하고, 파란 열쇠를 해방해 커터 다섯 개를 모두 통과시킨 뒤, 완성된 열쇠를 기차로 가져가 설치하세요. 그러면 철도가 운행을 시작해요. 기차 해금 단계
내 기차가 움직이지 않는 이유는?
네 가지 항목을 차례로 확인하세요. 보상 다섯 개 반환, 커터 다섯 개 모두 완료, 완성된 열쇠를 기차에 설치, 철도 운행 여부예요. 아직 끝나지 않은 첫 번째 항목이 다음에 해야 할 유일한 일이에요. 기차 문제 해결
파란 탑을 클리어했는데 기차가 여전히 출발하지 않아요
파란 탑 보상은 첫 부분일 뿐이에요. 해방된 열쇠는 커터 다섯 개를 모두 거친 뒤 기차까지 가져가야 하므로, 탑만 클리어해서는 루트가 절반만 끝난 거예요. Big Key 가이드
열쇠를 설치했는데 아무 일도 일어나지 않아요
열쇠를 설치하는 것이 파란 루트의 마지막 단계이므로 발목을 잡는 것은 루트가 아니에요. 그 뒤에도 철도가 잠잠하다면 기차가 출발하지 않은 것이며, 파란 탑을 반복해도 달라지지 않아요. 철도 점검
기차역은 몇 개 있나요?
지금까지 이름이 확인된 정류장은 여섯 곳이에요. 순환선에 더 있을 수 있어서 여섯 곳이 최종 개수라고 보지는 않아요. 정류장 목록
기차는 어디로 가나요?
섬을 한 바퀴 도는 순환선이에요. 표시된 여섯 개의 이름과 그 순서, 진행 방향이 아직 확인되지 않아서 여기서는 노선 순서를 그리지 않았어요. 루트 메모
기차는 역에 서나요?
플레이어가 직접 확인한 루트에 따르면 이 기차는 정류장마다 기다리지 않고 계속 돌기 때문에 그냥 지나칠 수 있어요. 기차를 느리게 하거나 멈추는 것은 기차 안의 레버예요. 정차 방식
기차는 어떻게 타나요?
지도에 표시된 정류장에 서서 기차가 올 때까지 기다리세요. 고를 수 있는 목적지 목록이 없으므로 탑승은 메뉴가 아니라 월드 안에서 이루어져요. 탑승과 이동
기차로 파란 구역이 해금되나요?
아니요, 방향이 반대예요. 기차를 해금하는 것이 파란 열쇠 루트예요. 그 효과는 섬 안의 이동이지, 파란 구역을 여는 것이 아니에요. ‘다음엔 뭘 할까요?’ 도구
빅 라이드는 어떻게 얻나요?
운행 중인 기차를 타세요. 빅 라이드는 탑승 자체로 얻기 때문에 철도를 해금하고도 한 번도 타지 않으면 얻을 수 없어요. 빅 라이드 도전 과제
High Button으로 기차가 해금되나요?
아니요. 기차는 파란 루트에서 나오며, High Button을 끝내도 열쇠나 철도는 진행되지 않아요. 기차가 있는 위치
Ring Room과 Trap Room이 퍼즐과 역으로 모두 표시되는 이유는?
서로 다른 두 가지가 이름을 공유해요. 기차 정류장과 도전 과제는 별개이며, 정류장 이름으로 검색하면 퍼즐이 아니라 정류장이 나와요. 정류장 목록
