A commuter has revealed how a "infuriating" phenomenon from other travellers finally caused her to "snap".

       Writing in The Telegraph, journalist Allison Pearson said an "endemic" trend amongst commuters of using their mobile phones on loud speaker finally pushed her over the edge.

       Ms Pearson wrote of a recent encounter with another train passenger dubbed "Extremely Rude Girl" (ERG), who was talking without headphones on a video call.

       Detailing the moment she bravely intervened, Ms Pearson explained "it was much louder than an in-person conversation, making it impossible to concentrate on anything else" and added that she told the fellow passenger: "Excuse me, that's enough. Could you please stop your phone call?"

       The interaction continued with the ERG, who replied that she could "do what I want" before Ms Pearson told her "no you can't". Revealing that the ignorant commuter decided to back down, Ms Pearson said she "felt the weight of approval" from everyone in the carriage.

       During the race to become London Mayor last year, Conservative candidate Susan Hall proposed banning noisy phone users from the capital's transport system.

       She said: "People deserve a safe and quiet journey home and yet under Sadiq Khan, the London Underground is less safe and less civil than it used to be.

       "I will overhaul the rules to ban disruptive anti-social behaviour and ensure that existing rules are enforced better by TfL staff."

       In a survey conducted in the late 2000s, the TfL group said: "Speaking loudly on a mobile phone is the most commonly witnessed type of inconsiderate behaviour on public transport according to new research conducted by Transport for London (TfL).

       "This was closely followed by loud noise from passengers' headphones and passengers taking up more than one seat or leaving bags on seats."

       In August last year, South Western Railway (SWR) released a series of nature-inspired 'Train Tracks' free to download and listen to for commuters.

       Together with the University of Oxford, a study of around 2,000 rail travellers found passengers were 35% less stressed when listening to nature soudscapes, such as bird song, flowing rivers and rainfall.

       Professor Charles Spence, from the University of Oxford, said it was likely the research "may have been one of the only" studies to be conducted using real commuters.

       He said: "It would be interesting to investigate whether the results could also be applicable to other forms of transport, such as long distance flights or lengthy drives."
