It happened again over the weekend when a young man from Brooklyn was struck and killed by an L train.

No one knows how he ended up on the tracks.

The MTA confirms to the New York Daily News that it’s in the preliminary stages of learning more about these protective barriers, like the sliding doors on the AirTrain.

“[It’s] very dangerous for kids,” said one woman.

“That’s what we need, especially during rush hour. It’s like so many people on the platform,” said another woman.

Regarding the cost, one idea calls for advertisers to foot the bill.

Sliding doors are also used on parts of the Beijing and Paris subway systems, as well as the airport train system in Atlanta.
