Hundreds of defibrillators will be installed on all of Metra's trains, officials said today.



The commuter rail line plans to equip its trains with nearly 300 of the automatic external defibrillators, according to a news release.



Another 125 of the devices will be installed "throughout work facilities and Metra police vehicles," the release said.



Metra is partnering in the effort with Northwestern Memorial Hospital, the Northwestern University Feinberg School of Medicine and Cardiac Science.
