SWR Class 455 ride - Motspur Park to Worcester Park with loud traction motors!

On the 10/09/2019, my friend was travelling on a SWR Class 455 from Clapham Junction to Worcester Park and discovered that this particular 455 unit had exceptionally loud traction motors. And he decided to capture the hellfire sound of the motors on video on the last leg of his journey from Motspur Park to Worcester Park.
