A railway firm has asked passengers to stop watching porn onboard their trains - telling them 'wait until you get home' instead.
Northern Railway asked customers to refrain from watching 'not suitable for work' content on their trains, which includes explicit material and inappropriate jokes.
The firm has also advised customers to avoid bad language and offensive topics.
Northern have said that they understand the train journey home is 'often the first opportunity' to 'view content', but that they should wait until they are home to do so.
Tricia Williams, chief operating officer at Northern, said: "We welcome millions of people into our stations and on-board our trains every year and access to safe and reliable internet is part and parcel of our customers’ expectations.
"It is important, however, that people remember that some content is not suitable for everyone to see or hear - particularly children.
"As such, if something is ‘not suitable for work’ it’s more than likely not suitable in our stations or on-board our trains either – so please wait until you get home."
Northern's wifi in their stations and on their trains is delivered in partnership with 'Friendly WIFI', a government-initiated safe certification standard for public WiFi.
Friendly WiFi aims to reassure users that the service meets minimum filtering standards, particularly in areas where children are present.
Bev Smith, director of Friendly WiFi, said: "We are excited to be working with Northern as a ‘Friendly WiFi’ certified train operator.
"They were passionate throughout the process to achieve the standard to ensure a great experience online for all their customers whilst travelling with them."
It comes a day after a woman was left fearing for her safety after a "creep" harassed and photographed her on a late night train journey has urged others to seek help after a group of strangers came to her rescue.
Agnieszka Narczynska, 34, was travelling alone on a ScotRail service between Glasgow and Lanark at around around 11pm on April 4 when a male passenger began to make advances towards her, calling her "gorgeous", before taking pictures of her on his phone.
As Agnieszka became increasingly uncomfortable, she began texting and phoning a friend to deter the man from talking to her, but when he refused to back off, she took the step of approaching a group of strangers for help.
Agnieszka said: “I was sitting on the train myself and there were only a few people around. I was at the back of the carriage next to the toilets and there was a guy sitting right next to me.
"Next thing, he started mumbling something about me being ‘gorgeous’. I didn’t make any eye contact with him, but he was staring at me," reports the Daily Record.
"I was texting and phoning my friend to pretend I was speaking to my boyfriend, but then I noticed in the reflection of the window that the guy was taking pictures of me. I looked at him and he wasn’t even trying to hide it. That was probably the most creepy thing about it."
