Embracing LED Technology

TDG specializes in LED innovations, continually introducing new technology which then becomes the industry norm. We carry a full line of LED, fluorescent and halogen lighting.

We draft specifications for a complete line of LED products for new car builds, retrofits or drop-ins. This means we'll easily adapt to fit your whole range of old and new rail and locomotive vehicles.

TDG is the industry leader in capacitive storage technology for evacuation and emergency LED lighting. You'll experience easy installation, fast recharging, long product life, and continued operation in the worst situations possible.

Meeting Tomorrow's Emergency Lighting System Standards

TDG is fully conversant with safety standards through active membership in committees for the American Public Transportation Association (APTA) and Federal Railroad Administration (FRA). In fact, we were invited to participate as key authors of the Vehicle Inspection and Maintenance Emergency Lighting Standards.

Our clients are assured we meet or exceed explicit and full compliance with current standards. And we have clear insight into future safety trends.

We build passive and active Low-Level Egress Path Marking (LLEPM) systems. And we create instructional and emergency signage in High Performance Photoluminescent (HPPL), vinyl, and metal materials.

This enables clients to meet the full complement of rail safety standards through one supplier.

Complete On-Site Design and Build

TDG stands out in engineering and building all products internally and on-site — from LED light engines or fluorescent ballasts, through to final assembly of the complete fixture.

This raises the bar on expertise, flexibility, and product availability. This results in developing complete lighting solutions which meet the performance targets required by our Customers.

Company History

Early Adaptability

TDG has been presenting innovative lighting solutions to the rail and public transportation industries since 1988.

We started by supplying lighting systems for refurbishment. We became experts in retrofits and drop-in replacement fixtures for units deemed obsolete or no longer supported.

New Technology

TDG excels at introducing new technologies to rail and transit products. For example, we were the first to install LED main lighting in commuter cars in 2003.

Full Process Control

We acquired Lexekon Electronics for the design and build of LED light engines and fluorescent ballasts. Thus, we can adapt to clients' needs right from the start of the process.

Capacitive Storage For Emergency Lighting

TDG released cutting-edge capacitive storage technology in 2006. This put a whole new face on LED emergency lighting systems in passenger rail and locomotive vehicles.

Meeting the Future Based on Solid Innovation

TDG continues to evolve and show the way in advanced LED lighting and circuit technology.
