This document provides an overview and update on Metrolink's implementation of Positive Train Control (PTC) technology across its rail network in Southern California. Some key points: - Metrolink operates 7 routes across 550 miles with 55 stations and carries 45,000 daily riders. - The Rail Safety Improvement Act of 2008 mandates PTC technology be implemented by 2015 to prevent train collisions and derailments. - Metrolink's PTC system will involve wayside radio locations, a communication network, and onboard train equipment to monitor train locations and speeds. - Implementation faces challenges with rugged terrain, long tunnels, and ensuring interoperability across host freight railroads. - Upgrades to

WHAT IS PTC ?Positive Train Control is a predictive collision avoidance system that provides a warning to train operators and then intervenes and stops a train before a collision or other hazardous train movement can occur.The primary purpose is to prevent incidents caused by single-point human failures by proactively stopping the train.PTC SYSTEM COMPONENTSAuthoritiesLocation ReportsData LinkBack OfficeServer (BOS)Signal StatusComputer-Aided Dispatching5.
