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列車の停車地点
- Ring Room列車の停車地点
- South Valley Beach列車の停車地点
- Sports Valley列車の停車地点
- Trap Room列車の停車地点
- Upper Hub列車の停車地点
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.
Open the Train Stops GuideShow the Train on Map
The Train is mapped as one landmark, so the map opens on the railway rather than on individual platform pins.
列車はどこへ行く？
線路は島をぐるりと一周する環状になっています。
現時点で停車地点の名前は6つ判明していますが、並ぶ順番、1周にかかる時間、どちら回りで走るのかはまだ分かっていません。順番が確定するまで、路線の順序は描きません。
まだ確認されていません。ご意見をお待ちしています。
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 Walk で列車を解放するには？
青の塔でチャレンジの報酬を5つ返却し、青いカギを解放して5台のカッターすべてに通し、完成したカギを列車まで運んで設置します。その時点で鉄道が動き出します。 列車の解放手順
列車が動かないのはなぜ？
次の4項目を順に確認してください。報酬5つの返却、5台のカッターすべての完了、完成したカギの列車への設置、そして鉄道の運行です。まだ終わっていない最初の項目が、次にやる価値のある唯一のことです。 列車のトラブルシューティング
青の塔をクリアしたのに、列車がまだ動き出さない
青の塔の報酬は最初の段階にすぎません。解放されたカギは5台のカッターすべてを通り、そのあと列車まで運ぶ必要があるので、塔をクリアしただけではルートは半分しか終わっていません。 Big Key ガイド
カギを設置したのに何も起こらない
カギの設置は青ルートの最後のステップなので、足を引っ張っているのはルートではありません。その後も鉄道が反応しないなら、列車が動き出していないということで、青の塔を繰り返しても変わりません。 線路のチェック
列車の駅はいくつある？
これまでに名前が判明している停留所は6か所です。ループ上にはほかにもある可能性があるため、6か所が最終的な総数とは見なしていません。 停車地点の一覧
列車はどこへ行く？
島を1周するループです。マップに載っている6つの名前、その順番、進行方向はまだ確認できていないため、ここでは路線の順序は示していません。 ルートのメモ
列車は駅に停まる？
プレイヤーが試したルートでは、この列車は各停留所で待たずに回り続けるため、目の前を通り過ぎることがあります。減速させたり止めたりするのは車内のレバーです。 停車の仕組み
列車にはどうやって乗る？
マップに載っている停留所に立って、列車が来るのを待ちます。選べる行き先の一覧はないので、乗車はメニューではなくワールドの中で行います。 乗車と移動
列車で青エリアが解放される？
いいえ、むしろ逆です。列車を解放するのは青いカギのルートです。その効果は島の移動であり、青エリアを開くことではありません。 「次は何をする？」ツール
ビッグ・ライドはどうすれば手に入る？
運行中の列車に乗ってください。「ビッグ・ライド」は乗車そのものから得られるので、鉄道を解放しても一度も乗らなければ獲得できません。 ビッグ・ライド実績
High Button で列車は解放される？
いいえ。列車は青ルートから来るもので、High Button を完了してもカギや鉄道は進みません。 列車のある場所
Ring Room と Trap Room がパズルと駅の両方として表示されるのはなぜ？
2つの別のものが同じ名前を共有しています。列車の停留所とチャレンジは別物で、駅名で検索するとパズルではなく停留所が表示されます。 停車地点の一覧
