Big Walk Big Ride Achievement: How to Unlock It

Activate the Train, then board its rideable platform. Unlocking the railway alone does not trigger Big Ride.

Big Ride is tied to the Train itself. The trigger is entering the Train’s rideable platform, not inserting the Blue Key or opening the railway.

Quick Answer

Complete the Blue route so the railway is active, then get onto one of the trains. Big Ride is tied to entering the Train’s rideable platform, not simply inserting the Blue Key or activating the network.

You do not need to visit every station or complete a full circuit.

This is one of the gameplay achievements. See the full achievements list

Where Are You Stuck?

Pick the line that matches your run. The Train system and the boarding step fail for different reasons.

The Train is still locked

That is a progression problem, not an achievement problem. Finish the Blue Key route so the railway becomes available.

How to Unlock Big Ride

Three steps. Only the last one is the achievement trigger.

  1. 1. Unlock the Train

    If the Train is not running yet, finish the Blue Key route first.

    Open Train Unlock Guide

  2. 2. Wait for a Train

    Go to an active station and wait for a Train to arrive.

  3. 3. Board It

    Step onto the Train and ride with it. Getting onto the Train itself is what registers the Train medal.

If the platform achievement has not updated, board again before replaying the whole Blue route.

What Actually Triggers Big Ride?

Big Ride is attached to the Train, not to the Blue Key unlock.

The achievement logic sits on the Train itself. When your player enters the Train’s rideable platform, the Train medal can be awarded. That is why unlocking the railway and riding it are separate states.

Unlocking the Train vs Riding It

Two different states. Only the second one awards Big Ride.

  1. 1Blue Route
  2. 2Train Unlocked
  3. 3Train Running
  4. 4Board Train
  5. 5Big Ride Trigger

Unlocking the Train

Finishing the Blue route places the finished key and opens the railway. At that point the Train system is available, but Big Ride has not fired.

Riding the Train

Boarding the Train puts you on its rideable platform, which is where the achievement is attached. This is the state that awards the Train medal.

Big Ride Not Unlocking?

Work down the list. The first line that is still true is the one to fix.

1. Is the Train actually unlocked?

If the Train will not move at all, this is a Train problem, not an achievement problem. Fix the system first.

Open Train Guide

2. Did you board the Train?

Standing at the station or inserting the Blue Key is not the same as entering the Train trigger. You have to get on the Train.

3. Did you get onto the Train itself?

The station platform, the station building and the railway unlock all sit outside the trigger. The trigger is the Train’s rideable platform.

4. Try stepping off and boarding again

The medal fires on entering the platform, so leaving and re-entering the Train surface is a reasonable way to re-check it. Treat this as a retry, not a required step.

5. Platform achievement delayed?

The in-game medal and the Steam or PS5 notification can update at different times. Check your platform achievement list before replaying the entire Blue route.

Train Not Running?

What Big Ride Does Not Require

These come up often, but none of them is required.

  • Every Train station

    Boarding the Train is the trigger, not collecting stops. There is no stop count to reach.

  • A full loop

    You do not have to complete a full circuit. Getting onto the rideable platform is what registers the medal.

  • A specific train colour

    More than one Train runs on the network, and no colour is required.

  • A specific station

    No station is named, so which stop you board at does not change it.

Anything beyond boarding the Train is not confirmed yet — feedback welcome.

Steam and PS5

On Steam, Big Ride is an achievement. On PS5, the same unlock appears as a trophy. The Platinum and the full trophy list are covered on the achievements page.
