Four new life-saving defibrillators have been installed at railway stations in Sussex thanks to the generosity of a woman whose husband died last year.
The defibrillators are easily accessible at the railway stations
Daphne Hutson-Pope asked friends and family to make donations to Sussex Ambulance Service to purchase the machines instead of flowers.
The equipment is used on people suffering a cardiac arrest before the emergency services arrive.
Haywards Heath, Brighton, Worthing and Hastings stations will all benefit.
Mrs Hutson-Pope used to work in the A&E department at the Royal Sussex County Hospital in Brighton.
She and her husband, Michael, were also both members of the ambulance service's public opinion group.
The defibrillators will be kept in accessible alarmed cabinets at the railway stations.
Mrs Hutson-Pope said she hoped her donation would give heart attack victims a second chance.
"The crucial time is in the first few minutes... and if something can be done in those few minutes the chances of a resuscitation are much, much greater than in the minutes after that where the chances go down rapidly," she said.
Sussex Ambulance Service said her generosity had enabled it to upgrade two of the older defibrillators located at Brighton and Haywards Heath stations as well as obtain two new ones for the stations in Hastings and Worthing.
The defibrillators, which are each worth between £1,500 and £2,000, will be used by specially-trained station staff and British Transport police.
