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.

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.
¿Adónde va el Tren?
La vía del tren forma un circuito alrededor de la isla.
De momento hay seis nombres de paradas identificados, pero el orden en que se suceden, lo que tarda una vuelta completa y en qué sentido circula siguen sin aclararse. No se dibuja ningún orden de línea hasta que se confirme.
Aún sin confirmar: se agradecen comentarios.
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
¿Cómo se desbloquea el Tren en Big Walk?
Devuelve cinco recompensas de desafío en la Torre Azul, libera la llave azul, pásala por las cinco cortadoras y luego lleva la llave terminada al Tren y colócala allí. En ese momento el ferrocarril empieza a funcionar. Pasos para desbloquear el Tren
¿Por qué no se mueve mi Tren?
Repasa cuatro comprobaciones: cinco recompensas devueltas, las cinco cortadoras hechas, la llave terminada colocada en el Tren y el ferrocarril en marcha. La primera que siga pendiente es lo único que vale la pena hacer a continuación. Solución de problemas del Tren
Terminé la Torre Azul, pero el Tren sigue sin arrancar
Las recompensas de la Torre Azul son solo la primera parte. La llave liberada todavía tiene que pasar por las cinco cortadoras y luego llevarse al Tren, así que terminar solo la torre deja la ruta a medias. Guía de la Big Key
Puse la llave, pero no pasó nada
Colocar la llave es el último paso azul, así que no es la ruta lo que te frena. Si el ferrocarril sigue en silencio después, es el Tren el que no ha arrancado, y repetir la Torre Azul no lo cambiará. Comprobación de la vía
¿Cuántas estaciones tiene el Tren?
Hasta ahora hay seis nombres de parada cartografiados. Puede haber más paradas en el circuito, así que seis no se considera el total definitivo. Lista de paradas
¿Adónde va el Tren?
Alrededor de la isla, en circuito. Los seis nombres cartografiados, el orden en que aparecen y el sentido del recorrido todavía no están confirmados, así que aquí no se dibuja ningún orden de línea. Notas de la ruta
¿El Tren se detiene en las estaciones?
Las rutas probadas por jugadores describen un Tren que sigue dando vueltas en lugar de esperar en cada parada, así que puede pasar de largo. Una palanca de a bordo es lo que lo frena o lo detiene. Cómo funcionan las paradas
¿Cómo subo al Tren?
Colócate en una parada cartografiada y espera a que el Tren llegue hasta ti. No hay una lista de destinos entre la que elegir, así que el embarque ocurre en el mundo y no en un menú. Subir y viajar
¿El Tren desbloquea la zona azul?
No, y la dirección es la contraria: la ruta de la llave azul es lo que desbloquea el Tren. Su efecto es desplazarse por la isla, no abrir la zona azul. Herramienta «¿Y ahora qué?»
¿Cómo consigo el «Gran vía»?
Viaja en un Tren en funcionamiento. El «Gran vía» sale del propio viaje, así que un ferrocarril desbloqueado al que nunca subiste no lo otorga. Logro Gran vía
¿High Button desbloquea el Tren?
No. El Tren sale de la ruta azul, y terminar High Button no hace avanzar ni la llave ni el ferrocarril. Dónde está el Tren
¿Por qué Ring Room y Trap Room aparecen tanto como puzzles como estaciones?
Dos cosas distintas comparten nombre. La parada del Tren y el desafío son independientes, y al buscar la estación obtienes la parada y no el puzzle. Lista de paradas
