This is a great train set. The first thing that I noticed about this train that caught my attention was how it emits real smoke like an actually train would plus has lights and makes actual train sounds. It's really neat, My kids played with this for hours!! This comes with a track that is unassembled which you will have to put together but it is very easy, we had this track assembled in 10 minutes or less. It also includes a train and 3 box cars. The train takes 4 AAAA batteries which are not included.
