Passengers have expressed their anger after they had to travel on trains jammed with people, most not wearing masks.
These pictures, obtained by the MailOnline, show holiday makers travelling on a Northern service from Blackpool to York.
The photographs emerged after hundreds of holidaymakers travelling on the line were left with little option but to cram into oversubscribed carriages.

Video taken on Saturday by one angry traveller showed few passengers wearing masks on a crowded train to the York line.
Christopher Crabb, 23, from Doncaster, was travelling on a service from Blackpool to York with his partner and their five-month-old on Sunday when they were forced to stand in a corner of the train by the toilet.
He described feeling “like cattle”, adding that his partner Laura Purdy, 29, had to balance on a slope in order to breastfeed.
Photographs showed three pushchairs squeezed into the disabled area of the carriage, as families ignored coronavirus rules – which call for masks to be worn while onboard public transport as well as social distancing.
Those few who were wearing masks pulled the coverings down below their nose and mouth, and Mr Crabb said rail staff did not try to enforce the rule.
In response to another passenger’s complaint over Twitter, Northern said: “We are unable to stop anyone from travelling it is each customer’s decision if they would like to board a busy service.”
