New Trackmaster to old Trackmaster adapters

Hey were pretty new to trackmaster, just bought 2 sets for my son, one seems to be the old fisherprice track and the other is what ive found out is called trackmaster revolution. disappointed because the track connections are different, is this your problem also? or is it tomy to fisherprice you have? ive tried looking for convertors but all i can find is tomy to fisherprice, does anyone have any links or solutions?
