The MTA says it will install protective barriers on platforms at three stations. This comes after Michelle Go was fatally shoved into an oncoming train in Times Square.

Many people, from board members to advocates, have been calling on the MTA to install platform screen doors for years. They say it reduces the amount of trash on the tracks — which can cause fires. And it would protect people from falling or being shoved onto the tracks.

Now, the MTA says it will try again — installing the technology at the 3rd Avenue L train station, in Times Square, and at the Sutphin Boulevard station at JFK Airport.
