Using the John Deere Battery - Powered Miniature Diesel Train Set is easy. First, make sure you have 2 AA batteries (not included) and insert them into the locomotive. Then, assemble the 8 curved and 16 straight plastic track pieces to form a 40' x 63.5' oval track. Place the battery - powered engine, tender, boxcar, tank car, and container car on the track. You can use the 3 - position switch to control the train: stop it, move it forward with sound, or move it forward without sound. The looping sounds like diesel revving, bell, and horn will make the play more interesting. When you're done playing, remove the batteries to avoid battery leakage. To keep the train in good condition, clean it regularly with a soft, dry cloth. Avoid getting the train wet or exposing it to extreme temperatures. This set is for kids aged 4 years and above, so make sure to supervise young children during play.
