The letter started with ‘Dear Mr Railway Man.’
Six-year-old Ella Porter wrote to the train service her father uses asking for the trains to make sure that they stay on time, as it jeopardises her cuddles with her dad each evening.
She wrote to Southern Rail: 'My daddy is always late home and I miss him very much. Please get him home on time. Daddy says you take all his money that is why I can't go to Disneyland. I really want to go to Disneyland.'
Her letter has now triggered a campaign, that is now being backed by thousands after the letter was posted online by her father Neil, with many people saying on social media that the rail company should treat the family to a holiday.
Neil Porter commutes on daily from East Sussex to London Bridge, where travel disruption and chaos has been caused by redevelopment works.
Southern Rail have apologised to Ella, a spokesperson said:
"Trains to Victoria and London Bridge travel over the most congested part of the whole of Britain's railway network and we are constantly pushing against the boundaries of what is physically possible on the infrastructure to provide as much capacity as possible to and from London."
