The first batch of 15 Automatic External Defibrillators was installed in the city’s Hongqiao Railway Station and Shanghai Railway Station on Saturday in a bid to offer first aid to people suffering cardiac arrest. Meanwhile first aid training will be offered to some 600 staffers working in local railway system, officials from the Shanghai Branch of Red Cross Society of China said.  It is the latest move to expand the installation of AED in public places, after Pudong International Airport and some Metro stations.
