About Us

Tetra Tech TAS, Inc. provides North American railroads the most technologically advanced, track-speed, fully autonomous track inspection system available.

Our RailAI® boxcar-based systems are currently operating in revenue service with North American Class 1 Railroads and the U.S. Federal Railroad Administration (FRA) ATIP program. RailAI is autonomously inspecting 24/7 with on-board artificial intelligence (AI) processing for real-time notification of defects.

Our RailAI system produces significantly more and higher value data than any other available system, providing five times the functionality at one-fifth the cost per mile of other systems. Combining multiple sensor systems on one track-speed platform eliminates the need for hi-rail and manned test vehicles, negates track occupancy concerns, and reduces risk to on-track workers. Available for lease or sale, the RailAI system provides image data for Tetra Tech to provide technical consulting services, customizing the AI system to achieve customer-defined track assessment goals. Tetra Tech additionally offers full system maintenance plans or will build a plan with the customer to share maintenance responsibilities.

The RailAI system has its roots in the radar and laser highway and runway inspection systems that Tetra Tech developed in the 1990s.

Building on that technology and processing expertise, Tetra Tech began developing autonomous railroad track inspection systems in 2015. Our work rapidly progressed from a manned test car to an unmanned boxcar in 2017, and finally, to a fully autonomous production model in 2019.

Tetra Tech TAS, Inc. is a subsidiary of Tetra Tech, Inc., a leading provider of high-end consulting and engineering services for projects worldwide.

With 27,000 associates working together, Tetra Tech provides clear solutions to complex problems in water, environment, sustainable infrastructure, and renewable energy.
