Spiral duplo pieces works great! Grandson hasn't gotten the hang of it yet, but that's why Im there... directions a re great...

My 5-year-old and I are toy connoisseurs, and we are having a blast with Imagine Trax! Easy to create new 3-D track orientations for unending imaginative play. Well made, pieces fit together and come apart easily and the multicolor joiners are just such a cool idea to bring train play to the next level — literally! Highly recommend Imagine Trax!

My kids aren't yet able to build this without help but they like playing with it once built. The instruction sheet had an error, but I was able to figure it out. The spiral is cool, and the pieces fit the Duplos well.

Tip: If you don't have enough half-size Duplos, you can use Legos wich are compatible with Duplos (but not the Imagine Trax pieces) and are the same height as the half-sized Duplos.

My kids have a lot of wooden track and they have a lot of Duplos. This set lets them build with both at the same time. It's fun to build really tall hills and to send trains under tunnels made of Duplos. The pieces fit the Duplos well and I'm pleased with my purchase.

Awesome connector blocks, perfect for a 4 year old master inventor! Love the ability to use the toys in new ways, and the blocks are super sturdy for hours and hours and hours... and hours of play.

Any fans of wooden trains must get these! Awesome risers for expanding your tracks.

Love these track accessories! my nephew loves to make his train tracks high off the ground, but got very frustrated when the objects he stacked underneath would fall. These are the perfect solution! He had so much fun building the track of his dreams and having it be stable! Thank you!

Came very quickly and can't wait to give to my son for Easter!

These are amazing for fans of wooden trains! Our kids love to have us build elaborate tracks, and it's great we don't have to store risers. We can just use the duplo we have!
