- A black motor
- A black holder for 3 1.5V batteries
- A white microphone block
- A transparent block containing a circuit board with electronics
- Two cables with colour-coded plugs

When everything is put together and connected correctly, you get a locomotive with tender. When you blow the whistle or make another loud noise (e.g., clapping your hands) the train starts. Another loud noise will make it stop.
