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 Diffuser火車站點
- Ring Room火車站點
- South Valley Beach火車站點
- Sports Valley火車站點
- Trap Room火車站點
- Upper Hub火車站點
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.
火車開往哪裡？
鐵路繞著島嶼形成一條環線。
目前已經確認了六個站點的名稱，但它們的先後順序、跑完一整圈要多久，以及行駛的方向都還沒有定論。在順序確定之前，不會畫出路線順序。
尚未確認——歡迎回報。
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
在 Big Walk 中如何解鎖火車？
在藍塔歸還五個挑戰獎勵，釋放藍鑰匙，讓它通過全部五台切割機，然後把成品鑰匙帶到火車那裡放好。此時鐵路開始運行。 火車解鎖步驟
為什麼我的火車不動？
按四項檢查逐一排查：五個獎勵已歸還、五台切割機全部完成、成品鑰匙已放在火車那裡、鐵路已經運行。第一個仍未完成的，就是你接下來唯一值得做的事。 火車疑難排解
我通關了藍塔，但火車還是不啟動
藍塔獎勵只是第一部分。已釋放的鑰匙還必須通過全部五台切割機，再被帶到火車那裡，所以光是通關藍塔，路線只完成了一半。 Big Key 攻略
我放好了鑰匙，但什麼也沒發生
放置鑰匙是藍色路線的最後一步，所以拖住你的不是路線。如果之後鐵路仍然毫無動靜，那是火車沒有啟動，重複通關藍塔也改變不了。 鐵路檢查
火車有多少個車站？
目前已標出六個站點的名稱。環線上可能還有更多站點，所以不把六個當作最終總數。 站點列表
火車開往哪裡？
繞著全島轉一圈的環線。六個已標出的名稱、它們出現的順序以及行駛方向尚未確認，所以這裡沒有畫出路線順序。 路線備註
火車會在車站停靠嗎？
玩家實測的路線顯示，這列火車會不停繞圈，而不是在每個站點等候，所以它可能從你面前駛過。讓它減速或停住的是車上的拉桿。 停車機制
我該怎麼上火車？
站在一個已標出的站點上，等火車開到你面前。這裡沒有目的地清單可選，所以上車這一步發生在世界裡，而不是選單裡。 上車與乘坐
火車會解鎖藍色區域嗎？
不會，方向正好相反：是藍鑰匙路線解鎖了火車。它的作用是在島上移動，而不是開啟藍色區域。 「接下來要做什麼」工具
我怎樣才能拿到「大乘一番」？
乘坐一列正在運行的火車。「大乘一番」來自乘車本身，所以解鎖了鐵路卻從沒上過車，是拿不到的。 大乘一番成就
High Button 能解鎖火車嗎？
不會。火車來自藍色路線，完成 High Button 並不會推進鑰匙或鐵路。 火車停在哪裡
為什麼 Ring Room 和 Trap Room 既顯示為謎題又顯示為車站？
兩件不同的事共用了一個名字。火車站點和挑戰是分開的，搜尋該車站會得到站點，而不是謎題。 站點列表
