NJ Transit will install a new warning sign designed to keep pedestrians safe.

The sign alerts people when a second train is coming after crossing gates are down because another train has already stopped at the station.

The new warning device will be installed at the Plauderville Station in Garfield.

That's where 13-year-old Michael Cabaj died in October after he was hit by a second train when he ducked under the gate after the first train had passed.

Transportation Commissioner Jim Simpson tells The Record newspaper that ducking under crossing gates is a pervasive problem in New Jersey that's against the law and "models bad behavior for children."
