Commuters at a Berkshire railway station are to be given the chance to learn how to save the life of a heart attack victim.
Commuters will be trained to use the defibrillators
Travellers at Reading Station on Tuesday, will be allowed to use Automatic External Defibrillators on medical dummies under supervision.
The station has five of the devices to ensure a rapid response to incidents.
The event is being jointly run by train operator, First Great Western and the Royal Berkshire Ambulance NHS Trust.
Richard Davies, community defibrillation officer for the Royal Berkshire Ambulance NHS Trust, said: "Thankfully, most people's only experience of defibrillators will be through TV hospital dramas.
"They may not know that there are now almost 700 defibrillators in 110 public places where members of the public congregate.
"As well as providing a rapid ambulance response across Berkshire we want to ensure that people know what to do in the first few minutes after an emergency occurs."
More than 20 members of the station's staff have been trained to use the life-saving equipment including British Transport Police officers and security guards.
Station manager Sonia Crosby said: "The exercise is designed to simulate a real heart attack on the station as closely as possible, so that we can test our reaction."
The devices are designed to be extremely simple to use by automatically recognising if a heart has stopped and advising the user to deliver a controlled shock.
