This is the hilarious moment when porn noises were broadcasted over a tannoy system to shocked train passengers, allegedly by the driver.
Moans and groans ring around the train carriage during the uncomfortable interlude on board a service belonging to South Western Railway.
Passengers laugh out loud as the grunting noises persist for over 30 seconds before the footage cuts short.
The video was uploaded to social media by Paul Brunton who praised the driver's "amazing multitasking."
He wrote: "My tube driver casually watching porn whilst leaving the tannoy system on…"
So far the tweet has resulted in over 1,000 retweets from social media users and thousands of likes.
One person said: "What a way to start the day mate!"
TFL said on Twitter : "Oh dear Thankfully not one of our trains or drivers."
A statement from South Western Railways said: “We have a policy of blocking inappropriate material, including pornographic websites, on its onboard and station Wi-Fi services.
"We are investigating this incident to establish how this material was broadcast on our service.
“Today’s incident is wholly unacceptable and we apologise to customers.”
British Nxivm 'sex cult slave' says dad found nude photos taken for 'master'
Earlier this year, two men who shot a porn film as they travelled just three stops on the Tube have been let off with a fine .
Porn star George Mason, 35, and escort Nicholas Mullan, 24, romped between Leicester Square and London Waterloo late at night in July 2017 and were filmed by a third unknown man as horrified passengers looked on.
The normal journey would have taken them less than five minutes but they managed to engage in anal and oral sex and masturbation on the Northern Line trip.
Mason later posted the film on Twitter and boasted: "It is outrageously horny we could not stop ourselves."
