Things got a bit saucy on South West trains on Friday when p*rnography was broadcast over the train's loudspeakers.
Railway bosses have apologised after passengers found themselves listening to p*rnography being played over a train's public address system.
Video posted on Twitter shows travellers giggling as the X-rated sounds filtered over the carriages' loudspeakers.
The blue broadcast – on an 11.30am service from Wandsworth Town to Clapham Junction – is thought to have occurred after a staff member accessed the adult material while a microphone was still live, but it is not known how the sounds came to be played over the public announcement system and who was involved.
The moment was captured for posterity by Twitter user Paul Brunton, who recorded the carriage's reaction and posted it online.
"Is that coming from the driver?" one women can be heard asking in disbelief.
South Western Railway (SWR), which runs the service, immediately apologised and launched an investigation.
But many on social media appeared delighted with the faux pas. “At least someone's enjoying the commute to work," wrote one.
SWR released a statement saying: "South Western Railway has 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."
