South West Trains have apologised for an announcement urging fat people to stay on their feet due to overcrowding.
The train was full of commuters when a member of staff reportedly said: 'We are going to be like sardines on this train, so can I ask that only slim people sit on the three-seaters.
'If you are fat then it is simply not going to work.'
One angry passenger on the service, which was leaving Basingstoke in Hampshire, told the Daily Mail: 'I am not necessarily a big person but most people are larger than those seats anyway. It's pretty disgusting. I would get fired if I said that at my work.'
South West Trains have since apologised, saying the comment, if it had been made, was unacceptable.
A spokesman said: 'All passengers are welcome on board our trains and we would find it unacceptable if that comment had been made by one of our employees.
'We run some of the busiest trains in the country and we do appreciate that space on some of our trains is limited.
'To provide extra space and seats for our customers, we are in the process of investing £250m in extra carriages and new trains.'
