In January 2023, the Long Island Railroad (LIRR) East Side Access project marked the opening of the first new major downtown rail terminal in the United States in 67 years and the first expansion of the LIRR in 112 years. <\/strong>The terminal provides Long Island with service to both sides of Manhattan for the very first time. <\/p>\n\n\n\n

Built 15 stories below ground, the project included an approximately 700,000-square-foot station, six miles of tunnel and 13 miles of new track, 3 train yards, 25 substations, and numerous supporting facilities with an expected 162,000 daily passengers.<\/p><\/div>\n\n\n\n

Our Role As Lead Designer<\/h3>\n\n\n\n

We operated as part of a fully integrated joint venture for the Long Island Railroad (LIRR) East Side Access project, serving as the lead designer for mechanical and rail systems in this complex Federal Railroad Administration (FRA) operating environment in concert with multiple stakeholders. As the systems engineering consultant, our design responsibilities included the following: <\/p>\n\n\n

    We are also responsible for designing infrastructure support elements for the positive train control (PTC) elements of the system that interfaces with Amtrak and New Jersey Transit trains. The system uses Alstom’s ACSES II, which is the current positive train control (PTC) system on the Northeast Corridor.<\/p>\n\n\n\n

    Designing An Integrated Security System<\/h3>\n\n\n\n

    We designed one of the critical components of this project \u2013 the complex, integrated electronic security system <\/em>designed and deployed to protect the infrastructure, facilities, passengers, employees, and operations. The system interfaces with the MTA Integrated Electronic Security System and is fully integrated with the security systems of Metro-North Railroad and LIRR.<\/p>\n\n\n\n

    Our electronic security system design incorporated state-of-the-art sensors to protect the tunnels and perimeters, multiple levels of access control, advanced video analytics to complement the intrusion detection system, and an array of video cameras, intended to provide the security monitoring staff with effective tools for tracking suspects anywhere in the system and to aid in dispatching responding law enforcement patrols. The video system further features a design to provide additional capabilities to emergency response to fire alarms and for use in managing crowding on platforms. More than 1,500 access control devices, and over 1,000 internet protocol cameras make up this comprehensive electronic security solution.<\/p>\n\n\n\n\t\t
