NEW YORK (CBSNewYork) — The Metropolitan Transportation Authority is looking into ways to prevent tragedies like the death of a Bronx man who was purposely pushed onto the tracks earlier this month.

Responding to an audience question at a recent NYU Law School forum, MTA Chairman and CEO Thomas Prendergast said the agency is looking at four devices that would detect motion on the tracks and alert the system, WCBS 880’s Paul Murnane reported.

The New York Daily News reported this summer testing has gone well with track-intrusion devices, and the MTA is looking to pay for the system in its $30 billion capital plan, which currently has a $15 million funding gap.
