Signal and communication systems are critical for the safety and efficiency of rail operations. With safety and risk mitigation top-of-mind throughout design, construction, and commissioning, VHB’s engineers and designers develop practical, effective signal and communication solutions that can be phased and built efficiently while maintaining existing rail service.
Partnering with project owners, contractors, and consultants alike, VHB offers deep experience, collaborative engagement, and a proven record of delivering thoughtful solutions for rail projects from simple to complex. Our multidisciplinary team brings decades of experience designing and upgrading rail systems for major transit hubs, including Boston and New York City. We have worked across diverse geographies, rail environments, and client needs—providing tailored solutions for signal and communication upgrades, new system installations, signal house design, and advanced technologies such as Positive Train Control (PTC) and communications-based train control (CBTC).
Leveraging in-house operations simulation modeling, our designers can test proposed system changes and pinpoint potential bottlenecks before they impact service. We translate this insight into targeted improvements, enhancing the reliability, capacity, and safety of rail operations while minimizing downtime.
Featured Services
-
Signal & Communication Systems Design
Integrating signal and communication systems into early rail infrastructure designs allows for smooth implementation and reduced construction conflicts. Our team works across disciplines to provide integrated signal and communication solutions that consider the entire rail infrastructure.
-
Testing & Commissioning
VHB applies robust commissioning plans, dedicated task forces, and flexible troubleshooting strategies to meet tight closure schedules. Our team develops detailed commissioning plans for system implementation to be carried out by the railroad or by a third-party commissioner.
-
Safety Engineering
Designing and testing systems such as PTC and CBTC to meet the highest rail safety standards helps prevent collisions, derailments, and service interruptions. Safety is of utmost importance on the railroad and rail transit system and is VHB’s highest priority in all that we do.
