London line's notice rule changed for disabled passengers
Disabled people using London Overground stations can now do so without having to book in advance, Transport for London (TfL) has said.
Wheelchair users - who need help getting on and off trains - were told to book at least 24 hours ahead.
TfL has also confirmed 46 of its overground stations will have step-free access by the end of the year.
However, campaigners point out that half the Overground stations are still inaccessible even with this change.
Paralympic gold medallist Baroness Tanni Grey-Thompson said it had long been an issue for her and she urged other rail companies to follow suit.
'No massive step'
Christiane Link, from campaign group Transport for All, said she was pleased she would not have to give 24 hours' notice on London Overground any more.
"I'm not a fortune teller. Not everyone knows when they are leaving the office," she said.
But she added: "Compared with non-disabled people it's not a massive step forward."
Forty-three out of the 83 London Overground stations are currently inaccessible from pavement to platform.
A TfL spokesman said that by the end of this year those stations becoming step-free include Brockley, Honor Oak Park, Hampstead Heath, Kensal Rise, Queens Road Peckham and South Tottenham.
