Project Overview

LIRR is currently working to integrate a Positive Train Control (PTC) system into railroad infrastructure. PTC is a system designed to enhance railroad safety by preventing train-to-train collisions, over speed derailments, incursions into established work zones and the movement of a train through a switch left in the wrong position. The United States Congress has mandated all commuter railroad main line tracks to install an interoperable PTC system, and LIRR is complying with this federal law. PTC integration into LIRR infrastructure was completed in December 2020. PTC is an important step in modernizing LIRR infrastructure, as well as maintaining the safety and reliability of the LIRR for future decades.
