Nottingham is one of 22 stations chosen to have one installed.
Each defibrillator comes with step-by-step instructions built into the unit which explain how to use it should someone suffer a cardiac arrest.
Having a defibrillator close when someone suffers a cardiac arrest greatly improves their survival chances.
According to the British Heart Foundation, for every minute it takes for a defibrillator to reach someone, chances of survival reduce by up to 10 per cent.
Donna Adams, EMR community engagement manager, said: “Each second counts when someone has a cardiac arrest, and with many thousands of people passing through our stations each day, they are ideal places to install a defibrillator.
"We are pleased to be able to contribute to such an important project and bring such vital equipment to communities right across the region we serve.”
