Metrolink receives critical funding commitments from South Coast Air Quality Management District (AQMD) to purchase its fleet of Tier 4 Locomotives.Ĭonstruction begins on the Perris Valley Line, a 24-mile extension of the 91 Line that is Metrolink’s first major expansion since the early 1990s. PTC monitors and, if necessary, controls train movement in the event of human error. PTC involves a Global Positioning System (GPS) based technology capable of preventing train-to-train collisions, over-speed derailments, unauthorized incursion into work zones, and train movement through switches left in the wrong position. RSD means trains in revenue service, or in Metrolink’s case, with passengers on board. In February, Metrolink achieves a milestone in Positive Train Control (PTC) when it receives authorization from the Federal Railroad Administration (FRA) and operates PTC in Revenue Service Demonstration (RSD) on the Orange County and 91 lines.

The approved Quiet Zone spans 34 railroad crossings in six cities and is the longest continuous Quiet Zone in the nation. As a result of these safety enhancements, the OCTA member cities’ applications to establish Quiet Zones are granted by the Federal Railroad Administration (FRA). Most of its $85 million cost is covered through taxpayer-funded Measure M, and is used to implement upgraded warning devices, additional gate arms, reconstructed crossing surfaces and medians, improved signage, and coordinated traffic signals. The Orange County Rail-Highway Grade Crossing Safety Enhancement Program is completed. The National Transportation Safety Board (NTSB) recognizes Metrolink as a national leader in PTC: “Metrolink's leadership to implement PTC is a model for others across the rail industry to follow." In September, Metrolink unveils its first fully-equipped Positive Train Control (PTC) test train. The engine offers significantly more horsepower, allowing Metrolink to move more people with more reliability. The diesel locomotives are the cleanest in the nation, and will reduce particulate matter and nitrogen oxide emissions by up to 85 percent, while using 8% percent less fuel.
