Setup and Assembly
Follow these steps to assemble your LEGO Duplo Railway Set. It is recommended to assemble each sub-set individually before combining them into a larger layout.
1. Assembling the 10428 Large Interactive Railway
This set forms the core of your railway system, featuring the interactive train and main stations.
- Begin by connecting the 16 rail segments to form a basic track layout. Ensure all connections are secure.
- Assemble the station building, car wash, and charging station according to the visual guides.
- Place the interactive Push&Go train on the tracks. Insert required batteries (not included) into the train if it requires them for sound/light functions.
- Position the four figures, cat, and other accessories around the track to create a vibrant play environment.

2. Assembling the 10426 Railway Bridge and Tracks
This expansion adds elevation and a bridge to your railway.
- Connect the 8 rail segments to extend your existing track layout.
- Construct the bridge structure using the provided Duplo bricks. Ensure the bridge arches are securely attached to the support pillars.
- Integrate the bridge into your track layout, allowing the train to pass over.
- Place the action brick and the technician figure near the bridge.

3. Assembling the 10425 Railway Tunnel and Tracks
This expansion adds a tunnel and a switch for varied track configurations.
- Connect the 10 rail segments to further expand your track.
- Assemble the tunnel model.
- Integrate the tunnel and the switch into your track layout. The switch allows the train to change paths.
- Place the action brick and funnel near the tunnel or switch.

Operating Instructions
The Push&Go Train (Set 10428)
The interactive train features a Push&Go motor. Gently push the train forward or backward, and it will continue to move on its own. To stop the train, firmly hold it down or lift it off the tracks.
Action Bricks
The railway sets include special "action bricks" that trigger specific responses from the Push&Go train when it passes over them.
- Red Action Brick (Stop): Causes the train to stop.
- Yellow Action Brick (Horn): Activates the train's horn sound.
- Blue Action Brick (Refuel): Simulates refueling sounds.
- Green Action Brick (Direction Change): Reverses the train's direction.
- White Action Brick (Lights/Sounds): Activates lights or other sounds.
Experiment with placing these action bricks at different points on your track to create varied play scenarios.

This image helps users identify and understand the purpose of each action brick.
Maintenance
To ensure the longevity of your LEGO Duplo Railway Set, follow these simple maintenance guidelines:
- Cleaning: Duplo bricks can be cleaned with lukewarm water (up to 40°C or 104°F) and a mild detergent. Rinse thoroughly and air dry. Do not use hot water, harsh chemicals, or abrasive materials.
- Electronic Components: The Push&Go train contains electronic parts. Do not submerge the train in water. Wipe it clean with a damp cloth.
- Storage: Store the set in a clean, dry place away from direct sunlight and extreme temperatures to prevent discoloration or damage.
- Battery Replacement: If the interactive train's sounds or movement become weak, replace the batteries with new ones of the correct type and polarity. Refer to the train's battery compartment for specific battery requirements.
Troubleshooting
Train Not Moving or Moving Slowly
- Check Batteries: Ensure fresh batteries are correctly installed in the Push&Go train.
- Track Obstructions: Verify that there are no small objects or debris on the tracks obstructing the train's movement.
- Track Connection: Ensure all track segments are securely connected and form a smooth path.
- Action Brick Interference: If the train stops unexpectedly, check if it has passed over a "stop" action brick.
Action Bricks Not Working
- Correct Placement: Ensure the action brick is correctly placed on the track so the train's sensor can detect it.
- Train Functionality: Confirm the train's basic movement and power are working correctly.
