I bought this train track set for my nephew's christmas gift, and it was a hit! The modular system lets him build vertical climbs, bridges, twists, and multi-level tracks, endless combinations mean he's still coming up with new layouts weeks later. The gravity-defying motorized train stole the show. Its ability to climb, go sideways, and upside down had all the kids gathered around watching in awe. It's not just fun and STEM-focused. The pieces click together firmly for stable builds

1 hour a day
The World Health Organization recommends no more than one hour of sedentary screen time a day for children aged 2 to 4, and says less is better. The American Academy of Pediatrics suggests a similar limit of one hour of high-quality programming for ages 2 to 5.

2 weeks
In a Danish trial, families cut leisure screen time to 3 hours a week for just two weeks. Their children showed fewer emotional difficulties and more kind, helpful behavior than children in families who carried on as usual.

2,441 children
A Canadian study followed thousands of children and found that more screen time at ages 2 and 3 was linked to lower scores on developmental checks later on. The researchers suggest screens may crowd out active play, reading and talking together.

Time with the people who love them doesn't come with a replay button. Give them something to build together, and the screen can wait.
It's one of the most common passions in early childhood
Nearly a third of young children develop an extremely intense interest, and vehicles like trains are among the most common.

And it isn't a passing phase
In the same study, parents reported these interests lasting anywhere from six months to three years.
Building is linked to sharper spatial thinking
Children who played with blocks, puzzles and board games often (more than six times a week) scored higher on spatial reasoning tests than children who rarely did.

Trains make cause and effect easy to see
Snap a piece in and the train goes. Leave a gap and it stops. Every build is a little experiment they can watch play out.
There's no wrong answer
No levels to beat and no instructions to follow. Every track is their own idea, which is exactly where creativity grows.
Switching off is so much easier when there's something better to switch to. Pick a moment in your day for a ready-made swap.
Instead of
Try this build challenge
No toy wins every time, and we won't pretend otherwise. But kids are far more likely to put a screen down when there's something hands-on waiting for them, and a track they designed themselves is a pretty good reason.
Ages 3 and up. The set contains small pieces, so it isn't suitable for children under 3. Please supervise younger builders.
Pieces snap together firmly and there's no wrong way to build. Younger kids can start with a simple loop and add more as their confidence grows.
No batteries to buy. The train is rechargeable, and the USB charging cable is in the box.
Yes. All WonderRail pieces fit together, so you can add another set later for bigger builds.
