What makes a good train set for Christmas?

The best train sets are not just something kids watch. They give them something to build, change or add to over time. That is why expandable systems tend to work well for Christmas: the first set can become the start of a bigger collection.

Infinity Racer Magnetic Train Christmas gift

1. Infinity Racer Magnetic Train

Best for: kids who love building tracks and watching their creations come to life.

Infinity Racer lets kids connect magnetic track pieces into different layouts, then send the rechargeable self-driving vehicle around the course. The track can be rebuilt again and again, which gives the set more replay value than a fixed railway.
