Fisher-Price Geo-Trax Train system Review

I bought this train set for my 5 year old for a first real train set.  It has been 3 years and many additional pieces later and he still plays with it.  There hasn't been many toys over 3 years that I can say the same thing about.  It is made with great construction and durability.  He has stepped on the tracks and it never budged.  I was really impressed with it.  It is a bit difficult to snap the tracks into place.  He did require some assistance with that when he first got it.  He now has all of the airport pieces to go with it as well.  It turns our living room into a huge city with all of the pieces assembles.  I guess if I had to say something negative it would be the size of it.  He has several different trains for it now and I plan on adding to it for many years to come.   This is one of the great toys I plan on keeping for him to hand down to his own children some day.  I am so glad I bought this toy.
