Pressing the buttons plays sounds and the lights flash. The left and right doors can be opened and closed. I have confirmed that all buttons 1-4 play sounds. 1. When boarding: "Thank you for using the Shinkansen today." 2. While running: "Gatan Goton" ← It's difficult to express the sound, but it's the sound you hear when riding the Shinkansen. 3. "Pee" - the sound of a horn 4. Upon arrival: "Thank you for using the Shinkansen today." *Batteries will be removed and the main unit will be shipped only.
