Largs residents have had their say on the latest explanation for the infamous ‘Largs Hum’ which first appeared more than 40 years ago.

Historian Robert Cathcart has put forward his own idea as to the source of the noise, which has confused Largs residents for decades.

Robert, who runs the popular Largs History Group, believes the electrification of the railways line is to blame, and how the sound interacts with the surrounding landscape.

He says the noise comes from the hum of the railway tracks bouncing off the surrounding landscape and echoing, creating a small noise only heard in certain areas of the town.

Now Largs residents have had their say on his theory, with some saying it is certainly a possibility.

James Wilbraham said: “From a physics standpoint, this theory entirely explains the source of the sounds, particularly in the areas where a peak in a soundwave meets another peak and is amplified.”

Caroline Le Good Morgan also backs Robert’s electrification theory, and says the timeline ties into the sound.

She said: “It sounds totally plausible, particularly when you investigate when the first reports of the hum came in simultaneously with the electrification of the railway.”

George Muirhead says the railway is a probable source of the noise, and a faint sound can normally be heard in the right conditions.

He explained: “It is obvious that it’s electrical and to do with mains electricity since it's a 50hz hum.

“You can usually hear it clearly from the railway’s overhead cable insulators after some rain.”

Stuart Kearney added: “Constructive and destructive interference will explain the variance without doubt. Theories are always the first step, the second is to prove and put to bed.”
