BROOKLYN - Following more than 40 deaths and injuries on subway platforms this year, the Metropolitan Transportation Agency (MTA) says it wants to install a barrier between the platform and the train tracks.

The MTA says it believes sliding doors will prevent injuries and accidents on platforms. The metal and glass doors would be part of a barrier along a platform's edge and would only open after a train stops at the station.

The MTA has not said how much the project would cost.
