Subway platform door test

Stand clear of the closing platform doors.

The MTA is considering adding sliding doors at L-train stations to stop riders from falling on the tracks following the deaths of two straphangers pushed in front of trains last month.

The L would be the ideal test spot because it doesn’t share track with other lines and is used by only one type of train, said Thomas Prendergast, the agency’s acting executive director.

That means the doors in the pilot program would only have to fit one kind of subway train.

It would likely be at just one station to start and spread to others if successful, he said.

Adding platform doors system-wide could cost over $1 billion, he said.

But it’s possible the agency will get funding from private companies, who could take a share of the ad revenue on the doors, he said.

In addition, the agency is planning an “aggressive passenger information campaign” to warn riders to stand away from the platform edge.

And they also are considering expanding the “see something, say something” campaign to ask riders to look out for the mentally ill.

Both suspects in the subway shoving deaths last month — Naeem Davis and Erika Menendez — have a history of mental-health issues, cops said.
