For a couple months now we have been potty training our oldest boy. It has been a long challenge and he has been going through potty charts and rewards. For his first reward we got him somethinghe had seen on on a recorded show that was recorded last year. It was the geotrax train system. Looked kinda cool. I looked online for a starter pack and it led me to get him the grand central station.

He loved it! it was awesome. it is easy for a child to put the trax together and they are not confusing. He liked the idea that the train can be played with off the trax too so he  drive it all around the house following it.

The remote is so simple for kids too. A lever that goes back and foward only to control the train so nothing difficult. All the tracks, roads, and whatknots are compatable for this set so you can get the skyscraper that has the roads and it will hook right up to the grand central station that has the tracks.  Very resonable priced too. so you can collect them all overtime and they will rarely get board with it. It is good for kids that are older too. I know my boy will probably play with this for at LEAST 3 or 4 more years (I HOPE!)

But be stocked up in the AAA batteries. It is not a battery eater, unless it is played with a LOT! almost all the individual stations have sounds and motions on them but those do not kill the batteries that bad. It has been almost a month and the fire station is still going but we change the batteries every 2-3 weeks on the train's engine because he uses it a lot.  

The only big complaint is that i have to buy these online so when i do not know when he fills up his potty chart it makes it hard to go out at the last minute to the store to get it i can;t find it.

But so far i have found a decent selection at toysrus.com
