A high-pitched sound that developed on a tramline in Nottingham during the hot weather has been keeping nearby residents awake.
Peter Nowakowski, who lives near the Highbury Vale tram stop, in Bulwell, said it sounded like the track was being worn down.
Nottingham Express Transit said it was a common problem caused by warm, dry conditions and has since lubricated the rails.
