The Long Island Rail Road plans to spend $14 million to replace six escalators that were upgraded less than two years ago.
Now the escalators have sensors that stop them from moving if something is caught.
All of the escalators were offline Tuesday morning at the Exchange Place PATH station in Jersey City one day after one of them suddenly reversed direction and five people were injured.
The escalator had been shut down for six months to undergo repairs.
The railroad took on the project following the death of an 88-year-old woman who was killed in an escalator accident earlier this year at the Lindenhurst station.
