My sister has a number of Geo Trax sets for her two kids and they enjoy it so much that I thought I would go ahead and give it to my littlest daughter for Christmas. We bought the Geo Trax Grand Central Station for Emma at Toys R Us for $50. We thought it was kind of a lot to spend on a toy, but it did come with a lot of pieces.
When I opened the box I thought it was going to be impossible to assemble because of the amount of pieces it came with. But, the instructions were super easy to follow and even my three year old daughter was able to help with the assembly.
Emma has since had such a blast with the Grand Central Station. It came with one motorized train that moves around the track and has sound. It also comes with the remote for the train so they can stop and start it. You can even make the train go backwards.
We have since bought additional pieces for our set to add on. There are a ton of accessories that you can buy for it for additional fun. The pieces do take up a lot of space so I recommend you get a large plastic tote with a lid to store it when not in use. Otherwise this Geo Trax set gets two thumbs up from me!
