SYSTRA is a pioneer in the application of Systems Engineering practices to the transit industry. Our team is the transit industry leader in introducing and applying systems engineering tools, processes, and practices to all project life-cycle phases including project concept through design and implementation through operation and maintenance. SYSTRA has developed and refined a comprehensive, documented, and repeatable systems engineering methodology that is consistent with the international standard ISO/IEC 15288:2002(E), Systems engineering – System Life Cycle Processes, the latest industry standard IEEE Std 1220-2005, IEEE Standard for Application and Management of the Systems Engineering Process, and the International Council of Systems Engineering (INCOSE) recommended practices. SYSTRA’s systems engineering discipline complies with the latest FAT System Safety and Security requirements and encompasses the following practices:
- Concept of Operations
- Requirements Engineering
- Systems Integration and Interface Management
- System Assurance including Reliability, Availability, Maintainability, Safety
- System Safety Certification & Independent Safety Assessor
- Verification & Validation
- Test and Commissioning
- Human Factors

Long Island Rail Road/Metro-North Railroad Positive Train Control Systems
New York, NY
A major component of the Rail Safety Act of 2008 requires commuter railroads to implement a Positive Train Control (PTC) system. Under this new law, Long Island Rail Road (LIRR) and Metro-North are required to comply with the Rail Safety Act and the PTC Regulations. These require each railroad to submit a PTC Implementation Plan (PTCIP) and PTC Development Plan (PTCDP) by April 2010, and submit a PTC Safety Plan (PTCSP) and other documents and complete the installation of a PTC System by December 31, 2015.
Positive Train Control System means a system designed to prevent train-to-train collisions, over-speed derailments, incursions into established work zone limits, and the movement of a train through a switch left in the wrong position.
SYSTRA is part of a joint venture to support the full implementation of the PTC system. Our team is providing engineering services to assist the railroads prepare documents and ultimately system designs that meet the intent of the FRA regulations pertaining to PTC.
The tasks include designing PTC systems that are similar in type to, and compatible and interoperable with, Amtrak’s Advance Civil Speed Restriction System (ACSES II) to a level required to complete the PTCIP and PTCDP.
