Southern Rail, who wish to remove on-board supervisors (conductors) have accused Kelly-Marie Blundell, Lib Dem candidate for Lewes, and Stephen Lloyd, previous MP for Eastbourne, of "unwarranted scaremongering".
The concerns over the safety of passengers arose after people spoke to both Kelly-Marie Blundell and Stephen Lloyd about feeling vulnerable while travelling late at night.
Kelly-Marie said; "Not only is Southern failing to run a railway, they are now failing to address the very real concerns of their passengers.
"Many women travel late at night, alone, from London back to Lewes, Newhaven and Seaford, and it is a genuine concern that CCTV cannot intervene.
"To accuse those people, and the peole who raise those concerns publically, of needless scaremongering, shows how little Southern Rail recognises the true needs of their passengers".
"We will continue to campaign for passenger safety, although I am sorry to say it appears Southern Rail simply are not listening."
