The initial close-up of a man working with complex electrical wiring and the question about 15km of cable and 3000 connections.

The video opens with a close-up of a man working on electrical components, then cuts to a wide shot of a yellow train, followed by a shot of the man inside the train's electrical compartment. The pacing is quick, intercutting between the man working and the train. The final shots show the man looking directly at the camera.
