Rail Systems Solutions

Partnering with Clients for Over a Century to Maintain and Create Safe, More Efficient Operations

Modern rail infrastructure is critical to our economy and the health and vitality of our communities. Whether moving consumer products or people, safe and reliable rail systems are essential.

Gannett Fleming is at the forefront of the industry delivering specialized expertise in rail systems today, as it has been since our entry into the rail market in 1918. Our approach is based on partnering with our clients to develop safe, efficient, and robust solutions. Using state-of-the-art tools, innovative technologies, and an integrated, multidiscipline approach, we address any rail systems scenario. Core to our business, Gannett Fleming offers a premier team of professionals who understand and develop a wide range of systems across:

  • Light rail.
  • Heavy rail.
  • Commuter rail.
  • High-speed rail.
  • Automated guideway transit.
  • Freight railroads.

Our experience tells us that rail and mass transit infrastructure is more than a collection of separate systems. We see opportunities to connect passengers, freight, and commuters by the most efficient means necessary, connecting into seamless rail networks. These opportunities to build industries and strengthen economies benefit from efficient and cost-effective rail systems solutions. Bringing together diverse stakeholders and developing solutions that address their needs is our mission. Combining our technical engineering expertise with planning, constructability, and maintainability skill sets enables our clients to align their infrastructure assets to accomplish their visions.

Gannett Fleming assists railway owners to achieve their critical missions through rail systems solutions, including track, traction power, electrification, overhead contact systems (OCS), signaling, and other train control and communications systems, as well as operations simulation and rail systems specialized project and construction management. In all we do, we keep our focus on your need for safe, efficient, constructible projects while supporting on-time operations, working relentlessly to deliver excellence on every project, every day.

Priorities in Project Delivery

Constructible Solutions

Our deep understanding and experience are not only in the design of rail systems. It also includes phasing, outage planning, and constructability. How can we achieve maximum efficiency during construction while minimizing outages and keeping operations moving at-pace? Our talented teams serve as your advocate and partner on every aspect of the project to turn your vision into reality. From initial planning through testing in the field and commissioning, our decades of project management fulfillment ensure that whatever the need, clients can count on us to deliver constructible solutions with increased quality, maintainable schedules and budgets, and most importantly, reduced risk.

Operational & Connected Systems

Maintainable and operational-oriented rail networks need to be seamlessly connected with systems solutions that work properly upon implementation. Coordination across disciplines is foremost in our approach to achieve maximum results while safely keeping trains moving.

By continuously adding new and vital technologies like our TAROS® suite of design and operations software, these simulation software tools solve the practical problems of planning, design, installation, operation, and maintenance. With the right people, technologies, and approach, we can create a smooth transition to each phase of the project life cycle through to operation while making sure operations are safe and efficient for years to come.

Integrated Approach

Gannett Fleming has experience and skills to take on any type of rail systems project, including on freight, passenger, and local networks. Our professionals take a systems-wide approach and understand a wide range of communication systems, as well as excel at integrating all components – from track, traction power, signaling/train control, and OCS – into successful broad operational systems.

For decades, we’ve been engaged in Class I and regional railroad projects, providing comprehensive systems services to railroad clients throughout the country. We are knowledgeable in railroad industry operations, use state-of-the-art technology, and recognize the railroad’s ability to strengthen business and customer service through system and operational improvements. Our rail system solutions seamlessly integrate into your operation, so you stay on track before, during, and after the project is complete.

Signaling and Train Control Systems

Railway signaling, from basic block signal systems to modern automatic train control, positive train control, and communications-based train control has been the foundation of our business for almost 50 years. We employ one of the largest signaling and train control teams in North America and are among some of the most prominent capital estimators. Our staff specializes in providing detailed hardware design and software programming. Our solutions integrate existing technologies to new advanced systems, assuring safety while optimizing throughput and customer service.

Traction Power

For transit agencies, changes in traction power system configurations can have a major effect on customer service, signals, and electrical performance, as well as capital and operations budgets. Our simulator software tools, including load flow modeling, help rail operators better manage planned and unplanned events. Operators can use simulation to evaluate the impact of varying scenarios, such as changes in schedules and train network configurations, as well as to model engineering designs of new systems and improvements to existing systems. These innovative tools are supported by decades of experience working with operators and owners in the planning, design, operation, and management of transit and rail systems.

Overhead Contact Systems

Bringing decades of expertise, we understand simple contact and trolley systems to the most complex, including both AC and DC systems. Our knowledge of bonding and grounding of rail infrastructure and adjacent third-party facilities, combined with broad experience in the planning, design, testing, and inspection of high-speed, commuter, intercity, and light rail catenary systems provide you with confidence that our solutions will accomplish your needs.

Diesel Rail Conversion and Electrification

As our world moves toward cleaner energy and electrification of its transportation fleet, rail systems will benefit from forward-thinking teams of transit professionals to study and plan for when sustainable railways make financial and logistical sense. Gannett Fleming’s broad portfolio of e-fleet rail systems, diesel conversion, and electrification projects means decarbonizing rail systems is possible and many times preferable in today’s push for sustainable transportation solutions.
