London's buses, tubes and trains have long had unwritten rules about behaviour on board — no feet on seats, let people off first, stand on the right of the escalator. Now there's talk of a more formal consequence for one of the most complained-about habits of all: playing music or videos out loud without headphones, a practice often called 'loudcasting'.
According to Secret London, the idea of penalising passengers who blast audio on public transport is gaining attention, with fines suggested as a way to tackle the noise that ranks among the top gripes of daily commuters. For anyone who has been trapped next to a phone playing tinny videos on a packed Central line train, the logic is easy to see. Transport for London already asks passengers to 'be considerate' and keep noise down, but enforcement has always been the sticking point — staff can ask someone to turn it down, yet there has historically been little in the way of an actual penalty.
The conversation matters beyond London, too. Cities around the world have experimented with similar rules; New York's subway voted in 2022 to make loudcasting a 'annoyance' under its rules of conduct, and transport operators elsewhere have tried signage, announcements and awareness campaigns. London appears to be moving in the same direction, weighing whether a fine — a model already used for fare evasion and antisocial behaviour on the network — is the right tool.
For visitors, the practical takeaway is simple regardless of what rulebook it ends up in: Londoners expect quiet carriages in all but name. Headphones for your own audio, phone calls kept brief and hushed, and speakerphone avoided entirely. Getting this wrong won't just risk a fine if the rules change — it marks you out immediately as a tourist in a city where subtle glances speak volumes.
The wider point for travellers is that etiquette on public transport is increasingly becoming codified. What was once just good manners is drifting toward enforceable policy in major cities, and visitors are often the least familiar with the local expectations. A quick read of the destination's transit norms before you go — whether it's quiet zones in Switzerland or phone bans in Japanese train priority cars — can save awkwardness and, increasingly, money.
