I believe the specification was that pressing the button would play the music horn sound, followed by the train whistle. I put in the correct batteries, but only a small "bup, bup" sound came out. It then played for a split second, but hasn't made a sound since. If anyone can repair it, please feel free to do so. Everything in the photos is included. Please refrain from purchasing if you are looking for a complete product or are overly concerned about condition, as this item has been stored by a non-professional. Please only purchase if you understand and accept the condition.
