"Several groups representing those with disabilities suggested that having more staff available to provide help ... would improve current levels of accessibility significantly. ... Increased availability of staff would also reduce fear of crime by those with disabilities and the elderly, who frequently report feeling particularly vulnerable."
(London Assembly, The Future Tube Priorities Investigative Committee, January 2003, paragraph 11.4)

So if increasing staff would make London Underground more accessible to disabled people and reduce fear of crime, we can only conclude that cutting up to 800 station staff jobs would make the Underground less accessible and increase fear of crime among vulnerable passengers.
