Train Signal Transportation System Walkway

Enhance train signaling system monitoring for safer railways

Exponent's multidisciplinary teams investigate the conditions of rail signal systems and their components and establish programs for their ongoing maintenance, repair, and modernization.

Train signaling systems solutions for a modernizing industry.

Rail signaling systems are critical components of rail transport, and malfunctions to these systems can cause delays, collisions, or other incidents. A signaling system provides control over the railroad and information regarding the operation and status of railroad components, including trains and wayside equipment. Exponent's electrical engineers and computer scientists are well versed in control systems implemented in hardware and software for managing systems and operations that are important to railroad safety, and have expertise in the telemetry, sensing, and communications technologies found in modern signal and train control systems.
