I have rated this item a little bit lower because it does not come with anything else besides these two train tracks. These two wavy train tracks need something under them to build a hill/bridge. It would be nice if you could buy a set with blocks that could be used to hold up the pieces. We have used a small blocks from our own block set to hold up the pieces and that worked fine.These are sturdy pieces that have been through three kids playing and playing and stepping on them and setting them up and taking them down and so on. They have made our train tracks much more fun.Well worth the money. Just be warned you will need something to 'hold up the hill/bridge'.Enjoy.
