All BRIO World toys work with each other to create an entirely customisable world that’s fuelled by children’s imaginations and endless combinations of play. Explore the world through play BRIO World is designed to help children discover and explore the real world. As they play with the recognisable vehicles, destinations and accessories, the realistic roleplay helps them to make sense of the world around them.

Tougher than Tough Maybe we're control-freaks, but we test our toys against tougher standards than the law demands. To be exact, we test our toys up to 25% more than the law demands. Toys that grow on trees Wood is one of our company’s strongest identifiers, and many of our wooden products have become icons in the world of toys. We’re proud to say that all wood used in our toys is from FSC (Forest Stewardship Council) certified sources.

Review: Works perfectly (for now) - Having seen the reviews from a year or more ago about faulty battery compartments I was a little apprehensive to buy but thought Brio have had a year to resolve the issue. The train works fine it was a little confusing at first as the initial red light went off and I couldn't figure out how to turn the train back on but trial and error, pressing buttons for various amounts of time, got it working (you need to hold down the middle button until the lights come on and it makes a sound). We've managed to update it from the app too (needed if you've got the fire, waterfall and crossing sets). I'm glad I bought the item as my 3 year old loves it and it had added another dimension of play to his brio train world.
Review: Great with the App - Connecting to the App is easy. Recommend you use the app to move the train then upload the additional sounds straight away as the Bluetooth connection will time out. My grandson is going to love this.

### ⭐ NEVER WORKED AT ALL
*by N***. on 10 April 2023*

Train not working. Straight out of the box, no way on earth to get it working. To be honest, I was not aware it was a "used but like new" product - I feel there is some misrepresentation here. I ordered this item, and it was brought to Canada after the fact by my mother, who gave it to my son, her grandchild, as a present. Terrible disappointment for my 5-year-old son! Now, obviously out of the return window, and I can find no way to contact the vendor. Appalling experience, would advise others to stay well away.
