This train set includes a steam or diesel locomotive with freight or passenger cars. All sets have 12 sections of track that make a large circle that is 40 inches across. Kids and train buffs alike will love the large, sturdy size of these trains as well as the realistic lights and sounds. The back of the packaging has the instructions and some fun facts about railroading. Sorry no set choice is available due to the fact they come in many different setups. This set uses 2 AA batteries (not included). For kids ages 3+. Price is for ONE set only.
